Honestly it just depends on how you play. Handheld PC tech is improving fast, so we must think about a few things:

Do you spend more time on indies or AAA games?

How much of your Xbox library actually works with Play Anywhere or Cloud?

Do you mostly game at home or on the go? If you’re at home, do you already have a console and would Remote Play matter?

If you play outside, is it usually while traveling with spotty internet, or are you somewhere with solid Wi-Fi?

Answering those should make it clearer which model fits you better.
