Never heard of the Pro having drift. It uses normal analog sticks. Put mine through the ringer and is still fine and first time I have ever heard anyone say drift about the pro. The Joycons use the faulty pads and Switch Lite. So the reports have never mentioned the Pro. So must be something you are doing to it.
Couple thousand hours of play on the switch so far. Pretty much entirely docked using a PRO. I've just exchanged them when they start to drift. Only other analog thumbstick I've ever had an issue with is on the N64. All four of those controllers got pretty played out by the end.
I'm not the only one...
