When comparing the software (not the self driving portion) I think the Model S/X is a much better comparison than the 3/Y since the S/X have they two screens like the Air. What I liked about my S (though I'm elated it's gone for the AIr) was that your could customize the center display content to your liking (you could do it completely with the steering wheel controls). I generally had tire pressure always displayed and power usage, but occasionally other info (especially during navigation). The Air (currently) does not allow much customization at all. The other thing was that you could define a few shortcut icons for often used items so you don't have to go hunting through menus or distract from driving. IMHO, that would be great for the Air, something I hope they implement.
I used to have to reset my Tesla periodically for the first few years of ownership, but not much for the last three years I owned it. The biggest thing was you could reset it while driving, and in a minutes or so it would all be back. To have to pull over in your Air to do a reset is an unpleasant restriction.
Although I had essentially zero significant problems in 6 years of S ownership , and a few significant ones in the first few weeks of Air ownership, I'm still much happier with the Air than I ever was with the S due to comfort, driving dynamics, a sane CEO, etc. Hopefully Lucid OTA updates will improve customization and fine tune ease of use.
