Have just ordered a Planck EZ 
White, RGB (Glow) with MX Browns (think I’ll prefer tactile switches on this keyboard).
I went for the EZ as I think the RGB lighting will help me get used to the layers (as I’ll set it to illuminate whichever keys are active on each layer). Once I’m used it, I would love to get either the Serika (v1) keycaps:
Or the MATT3O MT3 /DEV/TTY
From Drop. Btw, that’s on a Planck EZ^^ 
I do prefer the Serika keycaps… but I doubt they will be available again
