Why do people think Bison is easy to play with? Are there really that many monstrous Bisons around, if so please direct me to them so I can observe them.
Oh wait sorry this thread is retarded 
At a mid level where no one knows how to OS or punish crouch tech Bison tends to be very good. At higher levels that is a different story
What makes Chun so easy? I actually find her pretty difficult to play
The easiest is all 8 of the world warriors (Ryu, Ken, Blanka, Chun-li, E.Honda, Zangief, Dhalsim & Guile), Yun, Boxer, Claw, Dictator, Dan & T.Hawk
Hardest is C.Viper, Hakan, Gen, Oni & Sakura.
You have got to be kidding me. Sakura is basically at the same level with Dictator and Boxer when it comes to execution. My 10 year old nephew can use her. Just buffer cr.mk into DP constantly, use that cr.hp and if that´s not enough she can also combo into U1 and U2 from a jab without hard links or two bars of meter.
I can only speak from my own perspective. When I started playing SF4 and SSF4 these were the hardest characters to win with :
-Gen, Viper, Gouken, Hakan and Makoto
Basically constant frustration. Playing against Zangief was a nightmare and it was hard to deal with jump-ins. No momentum, did not know how to defend myself after knockdowns, couldn´t perform combos without eating reversal DP. Atleast with Gouken I was able to zone but it felt like I was handicapping myself in character selection lol.
-Seth, because you make more mistakes as a newbie and you dont have health
-Chun-Li, because she requires certain fundamentals. You need to understand how to use normals instead of just using special attacks. When I had around 1000pp it felt like a comeback was never viable after losing a lot of health.
As a result I just used Boxer and Bison and reached 1500-2000pp in a matter of days eventhough I still couldnt perform Ryu´s DP-FADC-Ultra haha.
…amazing
