My favourite one is Life's A Glitch at the moment. How about you guys? 

'H to the usky' Husky always for me. 
 
First one I came across and essentially introduced me to pro SC2 play.

Tastosis, THE CASTING ARCHON!

Hmm the commentator that OP posted is pretty good. I like the not-too-well-known commentators much more than the big ones.

I believe the dude i watch is called FORCE

My favorite is Day9 + djWheat.
 
Day9 is the encyclopedia, and djWheat is the "everyman". I don't like Tasteless + Artosis as much because I feel that Tasteless gets overshadowed a lot by Artosis.

" Tastosis, THE CASTING ARCHON! "

Day9 and PsyStarcraft 
 Psy is quite zerg-heavy though since he usually casts himself, but he does have his brother on his channel doing a Brutal campaign walkthrough.
 
I'll sometimes watch HDstarcraft or Husky.  Not so much Husky anymore though.  His screaming has been getting annoying for me.

OP seems very forced.  Entering that tournament that requires proof of advertising, huh?
 
Anyway, to the question, Tastosis and Psy.

I really like Husky, I find him funny and he is also a good venue for avid Professional StarCraft 2 fans (A.K.A. People who can't play StarCraft).

Husky's fun and all, but I ahve to go with Day9 for the knowledge bombs and the trumpets (and the midgets as well).

Day 9 first, Husky second, HD third 
edit: I seem to always have the raspy "delay iiiiiiiit!" in my head from Day 9 talking about people getting siege mode prematurely

The only right answer is Day[9] and Tastetosis.

Tasteless and Artosis are good, but one guy I particularly like is Nuke(thestars) on Youtube and Klazart was also pretty entertaining.

Husky, HD, and Psy in that order. I really tried to get into day9 but something about his commentary style just annoys me.  I know he's trying to be funny but the way he picks at player's mistakes comes across as rude to me.

HDstarcraft is the only one I know, and I like him.

Well, if we can only pick one Artosis. But Tastetosis is the best duo.

Huskateers, represent.

Husky, Psy and Tastetosis. 
Really do enjoy Day9 and Wheat at MLG though.

HD all the way.
 
"And allllll of theeeesee marines are going to go dooowwwnnn!!"

Day is the best, Artosis is 2nd. Tasteless has really fallen off since he used to cast WCG a long time ago. It really doesn't seem like he plays SC2 that much. He never casts anymore and he really doesn't seem to follow SC2 that closely, but Chill from TL used to be my favorite commentator in BW. He didn't cast that often, but when he would cast during the TSL it was just amazing. I would really love to see incontrol try to cast, since he doesn't seem to mind saying a player sucks when he thinks so. Artosis/Tasteless are way too ESPN-like for me, almost never saying anything negative about the players, everyone is "great" or "so high level".
 
Also, I enjoy listening to Diggity and Moletrap whenever they still put out a cast, even though they really were never the deepest commentators the nostalgia of watching their BW casts is too great.

I really, really like Day9. He shows you the intricacies of the players strategies.

" @rb_man: Husky is alright, but he doesn't talk very much about certain strategies that the top players use, he's commentated for awhile but still acts like he's unfamiliar to the SC2 esports scene. Just because he seems like the most popular commentator doesn't mean he's good. "

Husky!!!!!!!!!!!!

Day[9] and djWHEAT.  
Been following Marcus (djWHEAT) for as many years as I can remember with all of the stuff he's been commentating on (and even had a voice for a game character) 
And his weekly gaming show is also very, very entertaining. 

I really like HD. I haven't tried listening to many others yet though.

Day "The Thought Hammer" 9 is my favorite by far, he really knows his shit, and he just seems like a really cool dude.
