i'm using an mk mk84 at home and a matias mini quiet pro at work. the matias is really nice other than that i find it pretty ugly (i guess that makes it more discreet?), usb connects from the top (though it does come with a right angled connector), and of course none of my keycaps are compatible with it.
i was previously sent an MK84 with the wrong switches, but having tried both the wrong one and the replacement, it looks like rattle is an issue. i've read somewhere it shares the same oem as keycool. not sure if that's true, but if it is i guess it isn't too surprising since keycool 84's stabilized keys also have the same issues.
before that i was using a kbt race 2. no issues with stabilizers there (and they're more easily accessible since it's pcb mounted), but unfortunately it has a really odd 75% layout with multiple non standard keycap sizes and the usb also doesn't connect to the underside.
