I don't know that I have used the SL/SR buttons on my Joycons once in years, so I don't know that is a priority for me.

Drift is a problem, but I've had it more on PS5 controllers, frankly. I do think that at least some portion of drift issues are actually connectivity. The Switch fills in connectivity gaps with the last remembered input and if you have a weak signal that sometimes manifests as the stick being "stuck" off center.

I do think Nintendo should have gone for a slightly bigger battery and a more powerful antenna, although I see why they didn't want to. Still, as far as form factor and usability goes, those things are the best controller this generation, if not ever.
