Christian
Of all the stars who won the ECW title during WWE's incarnation, the longest and certainly one of the consistently best champions was Captain Charisma himself who put on great matches with the likes of Tommy Dreamer, Shelton Benjamin, and even a post-prime William Regal who still could put out a decent match here and there.
The Sandman
The hardcore icon holds the record for capturing the ECW championship on a record setting 5 occassions.
Raven
The second longest reigning champion in history
Shane Douglas
The longest reigning ECW champion in history who got people talking by throwing down the old NWA belt and saying all the greats that one before him can kiss his ass LOL. The franchise truly deserve the top spot.
Justin Credible
Credible was as credible a champion as the Miz was as WWE champion, seriously If this guy is your world champion sell your company to Vince.
