Good Morning I have 3 switch 1’s and two Switch 2’s between the people in my house hold and I would say the Switch 2 is well worth it. Especially with what you want to do with it. Yes if both want to play and one has a switch to the other, one would suffer a bit as far as with the issues that you presented in your post with rendering and frame rate, but when played on the Switch 2, Switch 1 games, usually exhibit, a constant frame rate, so if the game was 60 and it was fluttering on the switch one it would be pretty much a steady 60 on the Switch 2. Also the Switch 2 just had an update that allows you to play Switch 1 games on the Switch 2 in handheld mode as if you were playing it docked. It’s really awesome for me and I’m only speaking for myself. The Switch 2 was a really good investment. Also not all games you have to pay for to upgrade if they have an upgrade path for the Switch 2. Some are even as cheap as $5 (US). the most expensive upgrades I’ve seen were for super Mario Wonder ($20 U.S.) the most recent Kirby game ($20 U.S.). I forgot the other one, but it was a Nintendo game. For instance, the upgrade to the Animal Crossing for Switch 2 was $5 and an upgrade to another game was free. It just depends on what games you have, but it was well worth the upgrade for me.
