The Pro controller has drift issues as well (although less often)

Did you use/abuse the xbox/ps4 controllers as much as the Switch controllers? My guess is the amount of hours played is a big factor in wear and tear. Since the Switch is portable you have a lot more opportunity to play.

Switch: Barely used, and gently used. PS4/Xbox: Gets tossed around, used as a media center as well as for gaming.

After the first joycon replacement, we were even more gentle with it.
