Update on my SN30 Pro - I haven’t noticed any Bluetooth input lag whatsoever. I’m using an RPi 3B (not 3B+). I read on the RetroPie forums that any input lag over BT can be mitigated by overclocking and also that it’s less of an issue on the newer models, so if you’re using a RPi 4 you will probably be fine with BT.
