I'm still very early in my custom keeb journey, I've only built one board so far and already ordered a second one that I would hope the board itself would be my endgame. Switches will probably be something that is going to take time to figure out, I currently have tactile switches but my next board I'm going to try linear and go from there until I figure out what feels best to me. I'm not exactly super concerned with sound as before I was using razer clicky switches and basically any tactile or linear switch sounds so much better to me.
