Is it an Apple Extended Keyboard M0115, or an Apple Extended Keyboard II M3501? If the former, when you pull a keycap off, are there orange or “salmon” (kind of pinkish) sliders underneath? My favorite of the bunch is the M0115/M0116 with orange sliders. I’m not sure how the Matias switches compare, having only tried older versions of the Tactile Pro keyboard (they’ve made subsequent improvements to the switches), but as far as I understand, the “tactile” versions are intended to be similar to the orange alps switches, while the “quiet” versions are intended to be more similar to the AEKII’s cream colored alps switches.
As for whether the new Matias boards are superior.. Well, they are smaller and lighter weight, have a different sort of appearance, and I believe have a different feel to their keycaps. Whether those changes make them better/worse than the old Apple keyboards is subjective. They also use USB, have keys for adjusting the volume, etc., which might a be nice advantage.
