I guess you just don't? 8bitdo also comes with a kickass charging stand and their remapping software is kinda nice.
And you can get Xbox style face buttons set for it
The only things I don't like about it is not being able to have analog triggers and gyro simultaneously, and you can't map Star button to anything useful in Xinput mode.
Also keep in mind that there's 8bitdo Ultimate and there's 8bitdo Ultimate Bluetooth, only the latter comes with Hall effect sticks
I didn't like the fact that for the "pc-setting" in the 8bitdo you have to use the dongle, and can't use bluetooth.
also the kingkong2 pro has exchangeable abxy buttons, so you can change them to the correct layout for the thing you're currently playing on (which may be extremely useful with the little brother, depending on his age)
I think the comments I saw on ltt's review video(here: https://m.youtube.com/watch?v=2NfvzoDpcSM ) is that you don't. Since people point out the king kong 2(and pro) have input latency and their face buttons aren't at the same build quality as first party one.
Input latency(or variance of it) alone would not sit well with me.
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.
For what it's worth, I've been using an 8bitdo controller for years. I have one that was destroyed by my kids, and my other has been experiencing some odd issues with using rechargeable batteries draining even when it's turned off. I'm not sure what has caused the battery issues, but this is after probably 3 years of constant use so I've gotten my money's worth. I'm considering a new one but I have so many controllers as is it's just not worth it.
Sorry for not sticking to your to options. But. If your brother have a Switch, why not considering a Switch Pro Controller? Works great on PC, on Steam Deck, and of course Switch. I'm loving mine for PC gaming.
Because most people that have tried both prefer the 8bitdo ultimate or Gulikit over the 1st party Nintendo switch pro controller. (Also I'm not sure if the NSW pro is compatible with Android).
Also one thing that NSW doesn't have is hall effect joysticks.
Just being curious and not trying to persuade you in any way.
But why not Microsoft Xbox One Wireless Controller?
It has Bluetooth and all PC games I've played works flawlessly.
