Well, which of these achievements is the most impressive?

Ultimo Dragon's holding of 11 titles, that, to me, is impressive to the fact that he was one of the best at that time in his generation by holding those titles. That is the most impressive and what's more impressive is that the titles were international, they weren't just in 1 country. The J-Crown, 8 different jr. / lightweight titles, the NWA Middleweight Champion, WCW World Cruiserweight Champion and held a 6-Man Tag Team Title as well. Holy freaking s*it! No one can match that in today's wrestling world
