Going with Raiden. Gray Fox was great for his time but no one can deny the absolutely insane feats Raiden accomplished.

Gray Fox at his best could only hold up and damage Metal Gear Rex, Raiden threw a new modified Ray (arguably much improved from past versions) like it was nothing. And of course, let's not forget all the amazing feats Raiden performed MGS4 (he halted an Arsenal Gear-sized submarine for crying out loud with only ONE ARM) as well as in MGR (threw down Excelsus on its back and chopped it to pieces with its own arm blade)

Now you can argue that sure that's all just based on strength but I'd honestly argue that it's biased to dismiss Raiden's experience. That said, Raiden has the advantage of advanced tech and PROLONGED battle experience against evolving enemies (sorry but Gray Fox died much earlier before anything weird happened to the MGS-verse). Let's not forget that Gray Fox suffered from a worst case of insanity, giving Raiden a clear edge with his revised mentality in MGR and new refined discipline.

Gray Fox was killed by Metal Gear Rex when he was already Cyborg Ninja form (sure it's piloted by Liquid but it wasn't even at maximum combat capacity). Raiden fought and defeated multiple Metal Gear Rays BEFORE he was even a Cyborg Ninja. Normal Gray Fox lost to rookie Snake in hand to hand combat in MG. Normal Raiden defeated Solidus Snake in a sword fight, who himself wore an exoskeleton suit (and if you're going to deny the skill that Solidus possessed in sword combat then I don't even know what to say to you).
