I'd rate Misawa as ace above Jumbo as ace because the sheer volume of classic matches can't be denied. But it should be noted that Misawa had much better opponents. Jumbo wasn't working with Kawada/Kobashi-caliber talent on a regular basis. There was Tenryu, and their feud was awesome, but it was also relatively brief. There was also Hansen, but Jumbo never really clicked with him. Then again, neither did Misawa. It should also be noted that it was Jumbo's work in the late 80s that set the table for what Misawa and company were doing in the 90s. Misawa didn't really do anything during his Tiger Mask run that screamed "future GOAT contender."
