They are both great fights... hard to pick which one was better. I would have to say Pac V Morales 1 as it was not a fight that marked the end of a Champion.
despite who won what rounds if Morales REALLY wanted to he couldve won basically every round in that 1st fight..he really dictated that fight very well..Pacquiao wouldve gotten literally killed vs a prime well conditioned Morales
not quite sure how someone can seperate these two great fights enough to say one is significantly better then the other, they are two supreme fights that come down to personal prefrence, i love Morales vs Pac 1, and that 12th round solidified it as one of my favorite fights of all time, but Tito vs Vargas was also a great fight, that had boxing, toe to toe battles, knockdowns from both sides and a spectacular ending.... I cant really seperate them, both great fights to me...
Vargas vs Trinidad was way more exciting. It had everything. Mexican vs Puerto Rican. I can remember Vargas vs Trinida a lot clearer than I can remember Morales vs Pacquiao I and vargas/trinidad was 5 years older than Pac/Morales so the one that leaves the longest lasting impression on the mind has to win.
