Al snow? I don't even remember his run.
I think as far as importance and making it relevant its probably for sure HBK, HHH, Xpac, Shane, D-Lo in no order
Outside of HHH, I think Xpac was legitimized the most by it. He was kind of considered underrated (like, people knew he could go, and pound for pound was as good as anybody in the ring at the time, but wasn't big enough to be taken seriously as a top contender type). HHH needed it alongside HBK.
But D'Lo was the belt's best champion.
