I have a Mediatek MT7921K, it’s using the mt7921e driver, 3 years ago the chip was new I think and not well supported in linux (problem with init/sleep/resume) but a lot of people fixed it, and mediatek released new firmware, and the driver is rock solid for about 3 years now, I’m using it on my daily driver working PC 8h/day, 0 problem, and use a BLE keyboard and trackball too.
