Kidd, if for no other reason then because deathstroke's design will anger him.
I have seen people in Soul Eater get stabbed in the chest and get up. I remember when when Sid knocked Black Star high up into the air, jumped up to him and used a tombstone to slam into his head and send him rocketing into the ground, in which he got up not too long from (I'm aware Black Star is the most durable of the group and that Sid was holding back, but he was still got blasted in the ground). This all never made sense to me. Sid was said to be a much better fighter then Maka and Black Star. I hate that I can't put it well into words and therefore I can't explain why I am confused on the level of power characters in Soul Eater are.
This is important because I don't know if Kid can be hit by real bullets and survive, but all things considered. Kid probably has a better chance at dodging and that's what I reluctantly base my vote on. This is quite debatable on who would win though.
@DBZ_universe: Your concept on Kid's symmetry craze is lacking my friend. Kid doesn't lose battles cuz of an oppenent's asymmetry, its ussually objects. For example, in episode 3 Kid didn't want to shoot the pharoah's coffin because it was an ancient, symmetrical object. But the minute the asymmetrical mummy came out, Kid destroyed it in a millisecond. Same that time where he battled Hologram Free in Episode 22. He couldn't fight because of the destroyed hallway he was in (which was once symmetrical), but the minute Liz and Patty pointed out the fact that Free himself is asymmetrical ,all the attention and anger was on Free. If anything, the asymmetry of Deathstroke would make this battle over even quicker. Plus the fact that Kid has Shimigami powers pretty much pwns any "skill" he might have.
@SpideyFan113: Sorry but I don't really watch the anime at all, I only watch the funny parts... I read the manga because it's better.. but I do know what you are talking about though, Also I know that the "not perfect symmetry" wont work cause later in the manga Kid forgets about symmetry because he wants change..
