#8 CM Punk
434 days. That is how long CM Punk's second WWE Championship reign lasted. The longest championship run since Hulk Hogan's first title reign between 1984-88 was an incredible achievement in the modern era of monthly pay per views and weekly television shows.
His first WWE Championship win came in one of the greatest matches of all time at Money in the Bank 2011, when Punk, on his last contracted night in the company, won the title from John Cena in an electrifying encounter and left the company with the belt.

Although that reign would be short-lived, Punk more than made up for it with his second. Defeating Alberto Del Rio via submission at the 2011 Survivor Series, Punk defended successfully against a wide array of opponents including Cena, Dolph Ziggler, Chris Jericho, Daniel Bryan and others before losing to The Rock in controversial fashion at the 2013 Royal Rumble.
Punk's dominance with the famous belt is unmatched in the modern era and is a lasting legacy. His dynamic promo's and superior wrestling ability are the icings on the cake.
