For this version of Superman/Clark I always go with Clark because he is the more attainable of the two. Like someone else above mentioned, Superman does tend to hold himself aloof while Clark has always been more "comfortable in this own skin" so to speak.

It really does depend on the version, though. The Superman movies definitely are more Superman than Clark (Superman always seemed perfectly comfortable relaxing while Clark always seemed a little more wound up.)

I honestly can't say which version for the comics... especially as they haven't really given us enough info on the new Superman/Clark for me to say which one is hotter/more attractive.

CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
-"Contact" (You're not her jinx, you're her blessing.)
