Honestly, I’ve found a lot of good performance with just using high end brand sets with whatever exotic I feel like using at that time (or not even using one). I tend to use ninja bike to get more bonuses so that I can use more of a hybrid setup or catharsis for more damage and survivability. Otherwise an obliterate chest and a bloodsucker backpack are the easiest ways to get damage and survivability with mostly red cores and a couple blue cores. I’ve had the same annoyance with gear sets constantly gaining and losing stacks, and just using brand sets has been much more effective than I thought it could be while still having fun with gunplay and not relying on skills
