Which do you choose? In a fight? And/or Which one is more popular to you? (PLEASE no flaming/insults. Let's keep this friendly)
IMO,Batman would be the more popular of the two. He's cool,dark,brooding. He has a cool outfit. He has cool gadgets/tech. Bruce Wayne is an all around cool guy as well.
As far as a fight,Superman would beat Bats down. My reasons are thus... Super did a couple of marvel/DC cross-overs he fought The Hulk and he fought Thor. They both were a draw.(Even though IMO.Thor won because his hammer is magical. And,Superman has a weakness to Magic.But,that is another discussion altogether.)
Sure Batman has a Kryptonite suite As well as various Kryptonite weapons. But,Superman is almost invincible. He draws his power from yellow suns(Earths) He has laser eyes. He can freeze with his breath. His body is pretty much indestructible. He can Fly(and move at super-sonic speed) Bats wouldn't even be able to catch him,much less beat him.
Remember when Atari 2600 was cool? Remember when 64 Bit gaming was top graphics? Remember when ColecoVision was introduced? Remember when Commadore 64 was one of the first gaming pcs? Remember having to use a phone modem to play online games?
