CM Punk. I'm not a big fan of the guy, but he exudes a certain confidence that just makes him look like a champion. Sheamus smiles too much, Santino I really don't need to elaborate on, Cody Rhodes is too generic for my taste, and LOL divas. I also like that you didn't include the tag champs, shows how much of a presence they have nowadays.
It's gotta be Rhodes, that belt just fits him perfectly for some reason, probably because it's such an awesome looking belt, and it matches his white attire. Hard to vote for Punk when he's still carrying that fucking toy belt around.
And Layla looks great as well for the obvious reasons. :ass
Cody I'd say but tbf he has made the effort to pretty much match his attire with the belt. Sheamus and the World Heavyweight Title look good together too. It seems to work. Punk has a confidence with the WWE title but that belt I'm not a fan of. It works for guys like Cena and Miz too but not for Punk.
Oddly I think that all the current champions really suit the titles and the designs but if I was going to choose one who looks better than the other then I'll go with Cody Rhodes who matches his white gear with a white title strap.
But, on a serious not, Punk needs a belt with more validity. If Rhodes could change the look of mid card title, certainly CM Punk should be able to have a WRESTLING CHAMPIONSHIP, and not a rapper's jewelry belt.
