Please recommend me a keyboard

I'm currently using a mac magic keyboard for my work macbook in home office and my desktop PC and I really like the feel of those thin keys. However, when gaming I feel the strain in my left hand near the knuckles when having my fingers on WASD for a long time. Contributing to that is probably the thin-ness of the keyboard itself. Also, my home office is basically in my living room where my wife watches stuff in the evening, so I'd really like the keyboard to be as silent as possible.

So, here's a list of what I need the keyboard to have/be:

  • ISO german

  • silent

  • a little thicker than a magic keyboard

nice to have:

  • numpad

  • keys like magic keyboard

  • a way to switch from mac to windows layout, so I can use it for work as well

Thanks in advance!
