There's no one guy, it's 10-15 who are equally great. Fox, Demayo, and a few others near the top then others like Sergio, Larry Scott, Levrone, etc. close.
Gustavo's not even in the top 20. Muntzer and Bannout had incredible striations, not quite as much size especially Bannout. Coleman & Oliva great size without great cuts. Arnold actually had good size but not great cuts.
