EDIT: In a match against both of them Luffy might win if he used Gear 3, but Ichigo might be quick enough with Tensa Zangetsu, so it could go either way, but I'm leaning more towards Luffy, he's much stronger than Ichigo i.e. their bodies.
Monkey D. Luffy aaaanyday.
Luffy is like one of the most powerful shonen jump manga characters i have ever come accross.
and the manga & anime is just pure win to boot.
on the other hand Bleach was awsome until the soul society rescue arc finished, then once the fillers came into the anime about those Bounto craps and saving Ishida, and the next stupid rescue arc for rescuing orihime began and those Espadas and stuff....i see it just recycling the same thing again and again....
