Honestly modern Motos are as close to the stock A. as you can get. Not really sure about E4, flashed it to LOS pretty soon, but g8 and, now, g30 has a minimal Moto integrations and some are actually useful, eg on g30 I finally adopted MotoActions (flash by chop-chop and camera by uugh doggo shake? lol) despite ignoring them for years, since XT720/RAZR. With g30 I even left the default launcher, it is good enough that I didn't bother.
