There's no excuse for how buggy and poor-performing they are, given GF's resources and what contemporary games on the Switch were able to do (namely, Xenoblade 3 and TotK both looked and ran better), but the experience of open-world Pokemon is really fun and there are quite few QoL improvements that are very welcome (particularly the option to change natures and IVs on a whim, and EV training being much more easily accessible). My assessment is mostly a second-hand one from my girlfriend's experience playing it (bought it for her last Christmas), and neither of us have played a Pokemon game since DP and therefore I can't comment on how it compares to Sw/Sh, but I'd say it's definitely worth playing.
