Both Jim Carrey versions.
Mask was smarter and quicker and has toon force.
Bruce had the powers of God but no wisdom or mental speed for it.
I mean hell he almost died for praying in middle of a road and truck got him.
God powers, but still mentality of a stupid feeble mortal.
In the arena and bloodlusted?
Almighty had him move the moon. I'm gonna give it to that guy.
I'm giving it to the guy who can make breasts bigger at will.
Bruce increased his physical/mental speed to the point where he could respond to millions of prayers in a very short period of time. Combine that with pulling the Moon, effortlessly creating and erasing stars, and a host of other esoteric abilities (e.g. granting prayers/wishes like a genie, meteorite impact on command, etc.), Bruce is way out of the Mask's league. Honestly, Bruce could just transmute the Mask's mask into anything that makes Ipkiss powerless.
