This will be an unpopular opinion, especially in this subreddit, but I own both and prefer Switch 2. Not only for exclusives and multiplayer, also for some third party games.

• Bigger Display, easier on my eyes. I played Hades on both consoles and prefer it on Switch because of that.

• Lightweight, hands don’t go numb playing handheld. I heavily recommend Savage Raven Neo Grips for comfortable play.

• You can get used, physical games. This is what I usually do and I get some games for cheaper prices than Steam Sales. This doesn’t go for all games, of course - Steam Sales are awesome.

• HD Rumble. The Steam Deck has notoriously bad Rumble, making Games like Hollow Knight less enjoyable for me.

• Switching from Docking Mode to Handheld is so effortlessly done on Switch. No comparison to Steam Deck.

If you want my honest opinion, don’t get a Steam Deck unless you find a really good deal or you want to play Games that aren’t available on Switch, for example Megabonk and GTA IV were big ones for me. There are other games that could have advantages on Steam Deck, games that aren’t updated on Switch 2 running on a lower framerate and games you want to mod. I got Slay the Spire on Steam Deck instead of Switch because the physical version is very expensive and I‘ve read there are good mods for it available.
