I'll go with RJJ. I think hes the best fighter h2h at and around his best weight, meaning if all the top guys fought each other in their primes I would expect him to win the most matchups. I cant say that for floyd. The guys that gave him serious trouble were nowhere near as good as the truly great fighters with similar styles and attributes. Duran Chavez Whitaker etc eat him up imo Also how does he deal with a Paul Williams? A younger Oscar? A younger Mosley? Tito? Meldrick Taylor? I dont even know how he would do against a Prime Spence or Crawford.
