Neither, for me its mostly if
1 - The ps5 is as quiet as the xbox
2 - If my nacon revolution unlimited is compatible with ps5 as I hate dualshock
3 - Price of PC parts, if there's good sales Ill choose PC over consoles
4 - The new Halo game, if it is as good as Halo CE then I might choose xbox
Power between the 2 consoles will be pointless, it's less difference than ps4 vs xbox one at launch (1.84TF vs 1.3TF) - 50% better GPU on paper, also the difference between 1080p vs 900p is more noticeable than 2160p vs 1800p, and to note the ps4 was a cheaper console.
This time the difference is way less, and real life will be less noticeable, and ps5 will be cheaper justifying the slight weaker GPU, more than ever it will come down to exclusives, specially now that both consoles will be backwards compatible with the previous consoles.
This tells me ps5 will sell the most automatically, because people will want to keep their libraries going forward, now more than ever because this generation a lot of people bought a lot of digital stuff.
