The Keychron K3 is everything you need in a mechanical keyboard—elegant, wireless, responsive, tactical, and customizable. The very words I'm etching out right now found their origin in my own Keychron K3.
It's slim size (notice the lack of a numpad) makes it highly portable, too. And while it is wireless, the charge hold isn't the longest, and the need to recharge has caused me to resign it to its wired state often.
Even if I upgrade in the near future, I still like it, and it'll undoubtedly serve you well.
