Most people I play offline tell me that they think Ken’s a very strong character; I agree with them (this includes people that have been playing since the early 2000’s, CvS2 era and they’re very strong. Best K-Groove Rolento in NorCal strong ;)).
Ken’s strength is that he has a counter to just about everything. Every good read can be converted to 20-50%. I believe he has better match-ups than Ryu. Ken’s fundamentals are about as strong as Ryu, you just need a little more patience as Ken’s normals and movement has to be used more sparingly since they’re not as safe. Ken’s gimmicks are also good, not amazing, so use them sparingly.
I believe that he’s the jack of all trades of this game. He has winnable bad match-ups, Sim being the only insane one.
To be good with Ryu and Ken in this game, I truly believe that you need strong SFII fundamentals. They’re gimmicks aren’t at the top so you need a strong neutral game.
I strongly believe that DRS Chris is one of the most fundamentally strong, with enough assertiveness to just throw unsolid shit out there to keep his opponent on his toes, in the US. Solid play can only get you so far, that’s when you put your own style into the mix(this is what I’m struggling with at the moment).
Ken’s amazing, you just can’t play him in auto-pilot mode.
