Which star power to use for bull? I know that Berserker can provide lots and lots of value due to infinitely chaining supers, but recently I discovered tough guy can really help in tight situations, but then it will cause me to have more trouble chaining supers. I think Berserker is more fun than tough guy but overall which build should I pick?

Btw the gadget is T-Bone missile
