I have two
Keychron K1 backlit keyboards, one with Gateron Red switches (connected to my Mac mini 2018) one with discontinued Gateron Yellow switches (connected to a cheap Wintel PC).
I also have a Keychron K8 backlit keyboard (Gateron Red) connected to my custom built Windows gaming PC. The latter keyboard is the best keyboard I have used since the Nineties.
Keychron also has RGB models since that is your interest.
