These are very useful, yes. They're effectively the same thing though, so they stack properly. Which adds to their value.

I find it difficult to imagine +Def buff being useful, though. Basically you'd need to double the gains from them across the board, plus scatter the different buffs to A and B. Like Andromeda and Amaterasu stacking to 40%+60% thus halving damage taken.
