I would love to play it on PC simply because of 60FPS, but honestly I simply cannot give up on the community. DGAF community is mostly PS4 and I doubt that will change with Destiny 2....even if there are people who'd be interested in PC version due to the framerate advantage.
You almost never see your character, you do however see their armour...and there is enough variation between armour, weapons, emotes and shaders to personalise your character.
If you don't see how you can feel connected to that then I don't k ow what to say.
There's probably a larger portion of DGAF that would move from PS4 to PC than there is currently playing on Xbox One.
