I know that a lot of people are going to fry me for not mentioning the Rock on this list, but aside from the fact that i just don't like the guy, i didn't see anything special in him, here's my list:
10.- Chris Jericho: He's the first ever undisputed champion, enough said.
9.- The Macho Man: When he was the champion, he kind of defied the odds, and his rivalry with Hulk Hogan was epic.
8.- Shawn Michaels.- Kind of like the same reason of the Macho Man, he also defeated the odds, and when he was a heel champion he was a lot of fun to watch, specialy when he formed Degeneration X.
7.- Bruno Sammartino.- The man was champion for a lot of years, he deserves respect.
6.- Hulk Hogan: He is who basicly put wrestling on the map, he wasn't the most gifted athlete, but he was a great entertainer and had many memoreble moments, i know that today he's a douche, but we can't deny the fact that he revolutionized the WWF.
5.- CM Punk: Ok, he may not be the most fighting champion, but the guy is very entertaining, he takes his roll very seriously.
4.- John Cena: The guy is the face of the WWE, wether you like him or hate him, he has been in some great matches, and in some great rivalries as well, he has done it all in the past 10 years.
3.- Edge: This guy has captured my attention when he cashed his money in the bank contract, he did it when no one expected it, no one saw it coming, and after that, his title reigns were memorable, like Cena, he had some of the best Rivalries.
2.- Stone Cold Steve Austin: A lot of people talk about the attitude era, this guy was the attitude era, he basicly reinvented wrestling, he started a lot of trends, he was the first superstar ever to stick it to the boss, whan he lost, he didn't cry or complain, he fought back, he was never intimidated, and sometimes he was very funny, talk about someone who defy the odds.
1.- Triple H.- I know that a lot of people are gonna go "what??", but this is the reason that to me he was the best champion, when he was the champion, he made everyone believe that to get the title from him they would go through hell and high water, he defended the title basicly with his life, he made the title prestigius, and who ever defeated him became a huge superstar, just ask John Cena and Batista, when he was a heel champion he was definitly the man to beat, he was the most evil, sadistic and twisted champion, and when he was a face champion, he was a fighting one.......
