I had been using the old Logitech K811 for years and loved it to death. I wanted to upgrade to a mechanical so I bought a Keychron K1 a couple of years ago. I liked that it was specifically designed for Macs and built like a veritable tank with a weighty all aluminum construction. I didn't like that it disconnected after 10 minutes and it was slow to connect. I also didn't like that the keys didn't have a proximity sensor for the backlight. On top of all that, I didn't like the tactile switches all that much.
When I saw the MX Mechanical I ordered it immediately with clicky switches, Mini size. After a week of using it I can say it's fantastic but not perfect. The build quality is nowhere near the Keychron, but it has the proximity sensor, connects seamlessly, and has software to control and customize buttons. I don't like that it has no buttons for screen brightness, but instead dedicates four buttons to dictation, emojis, screen capture, and mic mute. Sure, you can change the functions but the legend on the key won't be correct. It also aggressively changes the backlight strength based on ambient light and I find myself constantly turning it all the way up.
