From my experience, the 8bitdo Ultimate has been great. (KingKong 2 was not available when I purchased it)

I have it connected with the dongle to my PC (or Steam Deck depending) and when I want to play on PC I switch the button on the back to use the dongle. And when I want to play on the Switch, I change the toggle on the back again, and it stays paired to the Switch.

I don’t know enough about how KK2 pairs. Maybe it can do this too, not sure. I like that the charging stand allows you to keep the dongle in there and it connects to the pc through the charger.

And also, previous 8bitdo controllers have lasted me a long time.

Let us know what makes you pick one over the other. And happy gaming.

Yeah, this one affects where I was hosting my domains.

Any recommendations on what to do? Should I try transferring now? Would you just wait it out and see what happens?
