I'd probably go with Xbox given Sony's lack of Fs to give about their customers and their continuous DMCA abuse. The fact that Xbox shares a library with PC doesn't put me off in the slightest. If I need a system to hook up to my TV, then having a device that can share a library with my PC, while simultaneously having a few console features is still something of a plus for me.
PS5 has maybe 2 or 3 games that I'm kind of interested in but Exclusives have never been the draw to any particular platform to me. That and Sony are already considering moving to timed exclusives and shared platforms in the future. The real money isn't in exclusivity.
