Favorite/Least favorite units for each race?

Based on your current knowledge of the game, which units are your favorite and lease favorite for each race?

For me it's...

Protoss

Fave: I love the idea of a mobile pylon, and the notion of being able to instantly deploy an army anywhere on the map with warp-in. This is the unit I'm most looking forward to use.

Least Fave: Not too impressed with the Mothership and the abilities its been given. As the pinnacle ship in the Protoss army it should have more clever abilities than its current ones.

Terran

Fave: Tough to choose between the Hellion or Viking. I like the speed of the Hellian, and its linear AOE attack can make for some clever maneuvering. The versatility of the Viking also appeals to me. Both are accessible with a reactor, so I suspect both will be spammed heavily when playing as Terran.

Lease Fave: Easily the Thor, and this unit could very well be my least favorite of the entire game. It's unimpressive visually and sounds boring as hell. Although that new ability could have potential depending on what it ends up being. Glad they got rid of mechanical rebirth...that was just lame.

Zerg

Fave: The baneling is probably the unit I'm most excited to use in the new Zerg army. Sapper units are exciting to me, and I relish at the prospect of burrowing or dropping these for maximum effectiveness. They'll be a blast to ambush from behind bushes too.

Least Fave: Infestor. Love the fact that it can move underground, but its abilities are shaping up to be pretty lame and redundant. They could do so much more with this unit.

Protoss

Favorite: For me the protoss have a whole of very decent units and ideas so it's hard to choose. I will go with Stalker just because I really love blink.

Least Favorite: Can I choose Dark Pylon? If not then... Carrier maybe.


Terran

Favorite: Reaper. I love the D8 charges and the cliff jumping. Just love it.

Least Favorite: Thor. Find this unit very uninteresting, I don't see how it makes the gameplay any better and it feeds peoples' need for huge epic units which doesn't suit SC that well. It overlaps with other units and doesn't have a decent role.


Zerg

Favorite: A hard choice between Zergling, Baneling, and Roach all three of which I think are awesome. I will choose Roach because it's such a unique and cool idea. Oh man I also love Ultralisks too...

Least Favorite: Infested Terrans, if they are in the state they were in for BR2, if that has been changed then I choose Changeling because I think it's silly and won't be that useful.

Terran:
Favourite: Raven / Reapers
Dislike: Thor

Protoss:
Favourite: Immortal
Dislike: Nothing really, maybe Mothership a little bit.

Zerg:
Favourite: Zergling
Dislike: Changeling

Protoss:
Favorite- Stalkers. The blink will make things very interesting.
Least Favorite- Not 100% sure yet. I am a zerg player.

Terran:
Favorite- Raven. The turrets and HSM look very interesting. Very cool detection unit.
Least Favorite- Hellion. Im just not sure about this one, but it could turn out cool.

Zerg:
Favorite- Really hard to choose. I like playing zerg, and the idea of zerg in sc2, because all of the units are cool. Im looking forward to the queen and the infestor. The infestor looks pretty powerful to me even though I hear a lot of the opposite in forums.
Least Favorite- Changling. Im just not sure how useful it will be.

Protoss:
Favorite - Stalkers & Immortals!
Least - Carriers & Mothership...

Terran:
Favorite - Reapers & Marauders!
Least - Mules...

Zerg:
Favorite - Roaches & Corruptors!
Least - None...

Protoss:
Favorite: Dark Templar - death hides in shadows
Least: Collosus - it's too expensive, vulnerable, slow and clumsy

Terran:
Favorite: Battlecruiser - the new abilities will certainly diversify destruction from above
Least: Viking - losing the Goliath is a huge blow to the anti-air ability of the Terrans, and the airmode of the Viking won't make up for that

Zerg:
Favorite: Roach - this one's going to harrass players out of their wits
Least: Changeling - I can't find much use to this either then the first 1-2 times I use it to have a laugh

Protoss:
Fav:- Zealots
Least Fav:- Mothership

Terran:
Fav:- Thors & Reapers
Least Fav:- Vikings

Zerg:
Fav:- Ultralisk
Least Fav:- Brood Lord & Changeling

I'm just stating my favourites and least favourites of the new units only

Terrans:

Fav: Viking
Least Fav: Hellion (I feel that its attack style steals too much thunder from the Lurker. People call it a firebat on wheels, but 'mini-lurker on wheels' seems more accurate.)

Protoss:

Fav: Stalker - whether or not it's overpowered at the moment, it is undeniably a very intriguing unit that's destined for some epic plays :).
Least Fav: None at the moment o_0


Zerg:
Fav: Roach! I love this little guy! I just love ability-less Zerg units like Hydras, Zerglings and Ultralisks in BroodWar (kinda disappointed that Zerglings gained a non-burrow ability in SC2 :P). The micro depth comes from his unique regenerative properties. Just a brilliant example of incredibly elegant unit design.
Least Favourite: Overseer. I'd like it if they'd move detection back to Overlords and forget about Overseers entirely. Part of what made the Zerg in BW so unique was their method of detection. Saying that Zerg were 'detectorific' in BW is like saying that Terrans were 'firepowerific', but racial traits should be played up in SC2 to make the races more unique, not made more standardised across the three factions. It's not as if Zerg never had detection problems in BW. By requiring such a specialised (gas-costing, ugh) unit to detect invisible units out in the field, I can't help but feel that it cheapens the Zerg's uniqueness. I also feel that 'basic' units shouldn't always be morphing into bigger ones. It's ok when used on just a couple of units, but having morphs for Zerglings, Overlords, Mutalisks, and Hydralisks feels a bit too much.)

Terran
Favorite: Thor. Yes, I know it's not the uber killing machine that it appears to be but all of that will be changed with balancing. I just love the idea of the unit so I'm willing to bear with it :D
Least Favorite: Raven. Damn that name to hell! I was just starting to like Nighthawk, too! This is probably my most favorite "least favorite" as I still like the unit but I don't like the name .. not much of a reason, I know, but I was desperate for something to put here.

Protoss
Favorite: Stalkers. It takes something that I enjoyed from StarCraft (Early Dragoon micro) and takes it to the next level.
Least Favorite: Disrupter. There's nothing I hate about the unit itself but the model looks too much like a Trilobyte

Zerg
Favorite: Roaches :D:D:D:D
Least Favorite: Brood Lord. At the moment, I'm not really liking it but I'm sure it'll be changed for the better. At that point, I'll dislike the Changeling and Infested Terrans the most. Granted, the Infested Terrans aren't really a unit since they're a spell / ability but they seem pretty useless.

For StarCraft II units, in general (not anything specific, art-wise, stat-wise):

Terran:

:o Reaper Edit:Changed from Thor to Reaper

Zerg:

Protoss:
