Complete Arsenal = user has all powers.

Ultipotence = user has infinite power.

The first encompasses the second, which makes it strictly better.

(One power is "strictly better" than another if it can: do the same thing with lower costs/drawbacks/restrictions, OR, it has the same costs/drawbacks/restrictions but can do more things.)
