Still worse. Mechanical keys make the sound/tactile bump at the point of actuation. There is significant latency between that and your eyeballs, about as much between that and your ears (USB keyboard HID is typically polled at 10ms, Bluetooth is easily over 50ms).
Time to train an AI on your webcam to watch your fingers move and predict when they'll make contact!
Not the Cherry MX type, click and actuation are separate events. True with buckling springs though.
I've tried things like this, and they lag is very slight and variable, but is too noticeable for me to enjoy. There's nothing better than pure mechanical soundwaves
