I have both.

I’ve had my switch for many years at this point, while my SteamDeck is barely 1 year old. I probably wouldn’t buy a switch today if I didn’t already have one but since I already have one I still use it very occasionally for exclusives I’m excited for (well, actually used it a ton for TotK recently). I don’t have my Switch hacked and would just rather not go through the hassle of finding clean roms to download. The only Switch game I played on my Deck was Diablo III (because the PC version has no controller support or controller-friendly UI) but with Diablo IV now it’s unnecessary.

All that being said, there’s very few Switch exclusives I’m interested in for $60 anymore, even on the horizon, Zelda was probably the last one unless Mario Odyssey 2 is released before the end of the system’s lifetime.
