I have both an OLED Switch and a Switch 2. If you don’t have any other consoles then I’d say a Switch 2 is worth it. It’s getting a lot of games the Switch 1 couldn’t play and combined with the Switch 1 library there’s a lot of really great games. If you have a Switch already then I’d say it’s probably not worth it. Likewise if you have a PS4/5 I’d recommend playing games on that over getting a Switch 2. However having a portable “home” console is a really nice feature. Something to consider is unlike the past it looks like Switches will get more expensive in the short term rather than cheaper

In terms of games: DK Bonanza is a slightly worse Mario Odyssey, which is still a really good game! Kirby Air Ride is just ok. Mario Kart world is worse than 8 and Sonic Racing Crossworlds. Pokopia and Tamodachi are supposed to be excellent for people who like those games. Outside of that basically everything else is available on other systems
