Okay....I said it once, I'll say it 344,302 times. Cena does not decide how long his title rign lasts.
i'll go ahead and say that i prefer cena to the undertaker simply because i prefer randy orton to batista. cena's a little more personable (obviously). i don't like either of them - they both suck. i mean, the undertaker died, for godsake. get rid of that guy.
Undertaker is a huge piece of Wrestlecrap that for some odd reason became popular.
And that's part of the reason why he's such a success. He made a lame-ass gimmick work for a long. I will say he's average in the ring, hell, all of Taker's matches that are considered good to great were against:
Hart, Foley, Michaels, Angle, Lesnar... It was a bit difficult not to have a good match against those guys.
