Sadly, Superman everytime. Remember, in canon "Superman is as strong as he needs to be." and that means he is has the potential to be the strongest thing ever at any time.
Shame as I always liked Spidey more.
spidey would win though, he's like batman. He'd make a special web that had kryptonite in it and BAM Dead supes --- "One can not reflect in streaming water. Only those who know internal peace can give it to others." Lao Tzu GT - LucidChiba
CFB would still kick Superman's ass. No matter how powerful you are, there's always a CFB that can kick your ass. Superman might be "As strong as he needs to be", but CFB is "Stronger than that". --- "Cute" in an RPG is a kiddy euphemism for "Sexy". Online is the worst thing to happen to gaming.
Deadpool is the most badass anti-hero of all time, can't wait to play his game this evening lol --- "One can not reflect in streaming water. Only those who know internal peace can give it to others." Lao Tzu GT - LucidChiba
