I’m not sure I’d consider this a total upgrade - I have a Steam Controller and an 8bitdo SN30 Pro, and despite the 8bitdo one being newer and having been used much less, I wore through its original thumbstick rubber and had to replace it much sooner than the Steam Controller’s thumbstick cap, which hasn’t even worn through, it was just flaking.

Either that was a fluke, or the 8bitdo rubber isn’t as durable.
