100% perfect for both BK and BT, from what I've played. I also played through Beautiful Katamari and it seemed perfect as well aside from the katamari not showing up in the King's hand in the results screen. Oddly, this exact same issue happens in Katamari Forever via the RPCS3 emulator as well.
My joycon both got pretty bad drift after a year or so. I just don't use them. My Pro controller got it after about the same amount of time, and I was able to fix it by opening it up and cleaning it periodically, but eventually it stopped fixing the problem. I just use my PS5 controller for it now.
