Poise is the main benefit of heavier armor and its pretty huge. But it takes major investment to get to the 80-100 poise where you really see a strong impact. Other than that, resists are nice in certain cases, especially the one that resists bleed buildup since every fucking enemy in existance starts piling it on after a certain point in the game.
Yup, upgrading to the lionel armor with its massive poise lets me shrug off all kinds of shit. I still take damage, but I don't get knocked to the ground like a little bitch from most basic attacks.
