You gotta ask yourself how much work and potential troubleshooting you're down for. If you love tinkering with that sort of stuff, have fun. Nowadays, I have less patience and I'm down to fork over the money for it to all just work without my play session being me fucking around in the menus only for it to never look right to me. Also look into what framerate you'll get on Switch 2 vs whatever hardware you'd emulate on.

Ok. I dont have a Steam Deck so Im deciding between that and the Switch.
I have no idea how well those games would run through emulation though.

From what I've seen they run about the same as a switch 1. Say 720p 60 for Bayo 2 and unlocked hovering from 30-40 fps for Bayo 3 which runs 60fps on Switch 2. You could probably look up exact breakdowns on YouTube. On Steamdeck emulators I do see people run into audio and texture problems so be ready to troubleshoot if you go that route.

Getting a Switch game to run on a Steam Deck is a pain in the ass and you'll constantly find the performance isn't very good. I'd just get a Switch and save some money by homebrewing it to run those 6 games off a download.

Besides what the first anon in >>737707710 said (and I can relate in also being less patient in troubleshooting things nowadays that I was in my teen years or early twenties), Switch 2 will ALWAYS run games silently even the demanding ones, whereas the Deck is loud as fuck by comparison.
Nier Automata and Astral Chain are capped to 30fps but the Switch 2 makes the framerate entirely stable however, and the recently introduced handheld boost mode (which forces Switch 1 games to run in dock mode while playing handheld) polish the games to look better too. As a side note, I don't recall Nier Automata to struggle much on the original Switch 1 besides one tower room in the late game.
