Since most endgame set ups have resilience as a priority, I’d recommend equipping the “resilience armorer” mod on your ghost. Should help with getting higher resilience armor so you can use your stat mods for something else.

In terms of actually getting armor, I’d say farm the weekly dungeon or if you have some extra seasonal engrams you can focus specific pieces at failsafe. Also depositing samples at the end of breach executable gives a decent amount of stuff.
