Yeah, Franklin, Hendo, and Belfort were his toughest opponents that he dismantled. Other than Sonnen, a lot of the fights never seemed like a threat to him. The division had to be slow when Damien Maia got the title shot. Would have been really cool to see him challenge the elite 205ers. Got to give Jon Jones credit whether you like him or not, he steamrolled a pretty decent list of fighters althought some of them were leaving their prime (Rampage, Rashaad). But I think his run to the title and defending it has been more impressive than Silva's.
Silva's title reign didnt include two consecutive fights against welterweights, so Id say his reign was much more impressive.
