Which is more powerful?

[Infiltrator]

Yea, you can, but the bonus is just too good to ignore, at least imo.

[DGDobrev]

It indeed is, I can confirm that.

But still, not every playthrough must be conforming to the general expectations from a certain char - like warrior who must cast battle cry all the time to get that +rage medal, a paladin who must use paladins, inquisitors and priests throughout the game and use healing at least twice in battle, or a mage who must use flaming arrow at least three times per battle to get that wicked + mana medal
