My favorite combo is Balrog's Dashing overhead smash + low short to fierce headbutt Ultra/super. 
That and Gen's hand slap loop. 
Favorite move is probably Honda's down-towards roundhouse canceled into his command throw.  
So hype when that happens.

Cammy's Ultra.

probably Ken's ultra. i don't know what i like about it but it's so fun to watch 

The correct answer to this question is obviously Dan's gadouken xx supertaunt xx Ultra

I'm starting to learn Able and I really like his S. HP > Change of Direction > FADC > C. HP > Roll > Falling Sky or Ultra if you don't roll. It just looks cool.

Akuma's J. HK, st.HP xx Fireball, FADC, st.HP xx HK Tatsu, FADC, HP SRK Combo.

" Akuma's J. HK, st.HP xx Fireball, FADC, st.HP xx HK Tatsu, FADC, HP SRK Combo. "

Forward jump + high kick then sweep.  :)
 
Works in any Street Fighter game :)

" Akuma's J. HK, st.HP xx Fireball, FADC, st.HP xx HK Tatsu, FADC, HP SRK Combo. "

Hard air kicks with E. Honda. That man has incredibly large powerful legs!

I'm a Sagat player so my bread and butter against jump spammers is a simple high step kick into ultra or EX Low Tiger Shot. Once I pull it off once, they tend to not jump anymore.

" @Symphony: Actually jumping fierce/roundhouse into standing fierce into low short into dash upper loop into whatever is pretty handy too and unlike your insane full bar and 2 bar + ultra combos mine are easy to do, easy to land, effective, and meter conservative. Also it's not my fault if you get hit by the overhead every time fool that's just the way the game goes. Learn to grab learn to block. And I agree Sakura is one of my favorite characters. "

All of Bison's combo's are just too fun to watch :D

Jump in fierce punch cr. short cr. jab st. jab fp srk fadc air ex tatsu ultra. Taunt then disconnect. Does not get any better.

Oh hey, a predictable "its not my fault you suck" reply. Cause I totally said I can't beat Balrog. No it's quite the contrary. It's just boring as hell to see every single one play the exact same. At least flowchart Kens sometimes throw fireballs in the mix. "

Sakura's netural jump Roundhouse =)

Gez look at you eh, gettin all angry at randoms...your all grown up now "

I really like chuns st. strong into hazanshu.
 
People have a hard time dealing with that.
 
Buuuuuuuuuut the best thing shes got is hazanshu into super. Its hard to set people up into a situation  where its useful sometimes
 
I wish they switched her super and the ultra

IT WAS LATE OKAY?!  Oh crap, you already used that excuse, didn't you? :P "

Sakura ex tatsu, light kick reset, jab shenningans

Not even going to lie.. I love me some of that Guile-
 
FADC > Air-Throw
 
No joke. It's barely even a combo but I love it. It' so goofy.

sakura: j.hp, s.hp, lk.tatsu, c.hp, lk.tatsu, s.lk, h.shouken, FADC, s.hp, lk.tatsu, c.hp, ex.tasu, ultra, ragequit.

I use one combo as Vega consistently, and it's fun as hell to pull off. 
Focus Attack> Command Roundhouse juggle> EX. Wall Dive> Izuna Drop

I do like a good Abel combo. 
 
Fwd Mk  > St Hp > Hp COD > FADC  >  Cr Hp  >         ULTRA COMBO FINISH!

Makoto karakusa > stand fierce xx hayate cancel > stand strong xx hayate xx super > ultra. HYYYYYYYPPPEEE.

i like kens ultra

I like the move where you try to slam out Akuma's raging demon to counter a jump-in but catch the enemy with a jab on accident and it makes your demon just slide him harmlessly across the screen.

FA 3, ex TKCS, ex TKCS, ex TKCS, ex TKCS, TKCS, c.hp, c.mk, hk drill. 
 
For no damage at all. I do it whenever I can.

Flowchart is as dead as punk.
