Durability may be close, but otherwise I think Renji easily is stronger and faster. He could catch with 1 hand Mask's punches ten times stronger than when Mask faced bankai Kensei who's punch could level a city block at least when he faced Wonderweiss. It also made a crater just as backlash when he used it against Mask. Also despite Alibaba being flame based, Renji's baboon cannon turned Mask to ash instantly. It actually appears more potent than the flames of Amon although the scale may not be as big.
