@SirSpidey ben has to activate the Omnitrix to do anything, he is never just in Alien form. If he uses the Omnitrix and selects Alien X then yes he will win easily but even fast it take a few seconds to do and he would need to know how powerful the Superman is to know to select Alien X. So if Supes has no morals on then he wins because of pure speed. If supes doesn't want to hurt the kid and Ben uses Omnitrix then he will win. That is what this comes down to.
