Cleary for legacy has to be Hopkins I /Toney. On jaw dropping impressive I'd go with Malinga, Griffin II and long time champ/former champ Hill. Hill being the closest Jones ever went to full unification as Hill had the stones to travel and beat Maske in Germany. Then lost over 12 to Champ Michalczewski in Germany. This entire period is worth a deep dive at some point. There was so much fuckery going on with 175 and the onset of "champion in recess" for Jones. He vacates the wbc in 98, signs to fight Buster Douglas for a bogus IBA heavyweight belt, then changes his mind and pulls out. Graciano Rocchigiani beats #1 Nunn for vacant belt. Jones signs to fight him for the title...then Roy pulls out. So, the wbc then arbitrarily strips Champion Rocchigiani essentially restoring Jones. On its face pretty shady and silver spoon fed. Rocchigiani sued the shat out of the wbc, won in court and they were on the verge of filing bankruptcy. Ohhh so close . Excuse the rant . Tate and that ko was quality for Roy also. But as has been mentioned, he also had some absurd gimmes with overnight rotating "mandatories".
