Not a very lopsided one, I would say. Both have good damage, but Akira has speed and frame advantage.
That said, he is heavily punch reliant and we all know what situation a flurry of punches can get you into against Ryu.
Bayman 6-4 (formerly 4-6) Hayabusa is basically good against anyone he can outspeed. Also, Hayabusa has greater throw damage than Bayman, very good stuns, and gets more damage on Izuna holds than Bayman's expert punch holds. Hayabusa does not really need to fear getting held in stun because his air grab allows him to launch early and still get good damage and his stuns like 9K and 3P allow him to do that. Bayman will also have trouble getting hits on Hayabusa because of his sluggishness and fear of Izuna holds. However, Bayman can throw punish Hayabusa's many unsafe moves with 6 frame T and 10 frame 4T, annoy Ryu with parries, and use Tank roll.
The DDT and Atomic Crush do more damage than any of Ryu's throws but obviously they are breakable.
I actually agree. I'm inclined to say Ryu has the edge in this one.
Brad 4-6 Brad's unpredictability takes away Ryu's greatest strength. Ryu's lack of good lows also plays a factor here.
Not really sure the Brad match-up is 4-6. Brad has good crush options, running P and turtling techniques which work well against Ryu, but ultimately Ryu is faster and in general if you manage to be slower than Ryu you're in for a tough time (like you said against Bayman). I'm inclined to say 5-5.
Christie 4-6 Ryu has to go through hell to even get a hit on Christie. Throwing's not an option. You have to get lucky to hold her.
Christie's crushing, speed, string delays, kick-mix-ups, etc. raise hell for Ryu. She definitely takes the advantage.
Gen fu 6-4 Ryu has a far superior range game and can move around more than Gen Fu can. His throw and hold damage output is higher and their speed and strike damage is similar. Gen's are an annoyance.
Gen-fu lacks range (save that ridiculous 214P), but honestly he doesn't have to rush Ryu at range and most of Ryu's gap closing can be easily blocked or free-stepped (teleports). Gen fu's parry options, resets, crushes, etc. work wonders against Ryu. I don't see it being 6-4 against Gen fu.
