Tank or Bruiser? Which is better?

Which ability is better? Have a free AP spot on offense and going to put one of these on RB Bo..

Tank will help with the multiple avalanches ppl are gonna have

I'd probably go tank unless you're on old gen. 

Bruiser mainly helps with trucking and stiiff arms but on current gen you're usually better off trying to juke a defender rather than trying to run through them. Bruiser is also a bit redundant in my opinion at least if you're using bo's angry runs xfactor.

Tank helps against hit sticks so it's not the most important ability. But it can be very handy if your opponent is running avalanche anywhere. But that's also kinda niche since there's more valuable xfactors than avalanche on defense.

Both of them seem like luxury abilities to me but that's fine if you have nothing better to spend ap on.
