Ok I thought about it and I think Chris wins here.
Even if we restrict Chris with just 9-A equipment he still has plenty to deal with Guile and sonic boom zoning. Chris’ main win con, that I could think of, would just to catch Guile off guard with a flash grenade and just KO him or kill him (These wouldn’t try to kill each other tho, to much of a hero both of them), either that or restrict Guile’s movement (or what’s left of it) with like a pulse grenade or shock grenade and KO him or kill him from there. Hell, Chris doesn’t even have get into a fist fight with Guile, he could use the stun rod and poke him from a distance. If it does come to CQC, Guile does have an advantage in battle IQ but Chris is hilariously stronger than him that
he could 2 touch Guile (But not like 2 combos, literally; Light, Medium, Dead), plus Chris’ battle IQ isn’t too bad and might be just on par or below Guile’s.
Guile’s main win con is to spam sonic booms, wear down Chris and KO him from there. However Chris is durable enough to take multiple sonic booms and could reduce the damage via a melee vest or bulletproof vest, plus he could just pop a green herb and recover every bit of damage Guile does.
I vote Chris Roidfield
