I would like to add in my fourth favorite Clark Kent is Kirk Alyn. Like George Reeves and Dean Cain, he portrayed his Clark as a real man, not a wimp.
I also liked Henry Cavill's portrayal of Clark, but I don't think I saw enough of him in MoS to pull him into the top three.
Actually picking my favorite Superman was the most difficult of the three questions. Or actually, my second and third favorite Superman(s). Although, I haven't seen all of the original AoS or the Superman film serials, from what I've seen Superman doesn't have much interaction with the other characters beyond flying in to save the day and flying out again (more so with Kirk Alyn's Superman). Perhaps that will change as I see the rest of the series. I liked Henry Cavill's Superman as well, but again didn't feel like I saw him enough to pull him into the top three. But, despite, his helmet hair (stolen from Dean's Superman, probably) did consider him quite hot.
