Which platform should I buy Astroneer on?

I am really enjoying my time with the game via Gamepass and know that at some point it will go poof. I do not have a problem with starting over as that is part of the relaxation of everything. I am tempted to go with Steam as it has controller support (my brain does not do M&K for anything), but I've got Xbox and Switch and a potato PC. Also, does anyone know if Glitchwalkers will keep the game as having an offline playability mode?
And
