Do you like watching them more at welterweight or did you like them better at the lower weights? For me I perfer Mayweather more when he was in the lower weights. He was a much more exciting and all around better fighter to enjoy(not talking about skill wise). I was watching a few of his older fight and he was very exciting to watch....much more then the current Mayweather who is still an incredible fighter just not as crowd pleasing. As far as Pac goes I like him much more now. I will always love watching his featherweight wars with the mexican fighters however now he is a much more complete fighter and has way more to offer. He is also very leathal at welterweight.
Yep floyd has mastered his craft and honed his skills as hes goten older. Down at the lower weights he didnt use smarts as much but was willing to mix it up and threw more combinations with speed and power. The only thing is that made him more hittable. There is pros and cons. About pac i prefer him at the higher weights as he now has much better skill and still fights at a relentless pace and is really explosive.
At 135, Floyd was a more exciting fighter than he is now, but he is light years ahead of where he was skills-wise than he was then. Pac is a much more dynamic and exciting fighter at 140/47 than he was at the lower weights, plus has developed true KO power as he's moved up.
