Pac has heavy hands. Not in the sense that he has bombing power, but that he has a lot of weight emotionally so he won't crumble like Garcia will when he feels the heat just like Broner did.
Manny wins for me. Ill say UD. Danny waits too much during fights now as the years have been passing. Still a very dangerous left hook, but he freezes when flurried upon or pressured. And Manny still throws combos in 3s and 4s. He would give Pac a better fight then AB thats for sure, but even at 40, Manny would outhustle and outwork Garcia IMO.
