But, yea OP, I vote the pure as well. The poker is the same layout as a full size board, so the layout is really natural. I can go back and forth from a my filco or Rosewill board and the keys are the same shape and location.
And based out the amount of research you are putting into to this, I have a strong feeling you will get into keycaps, so the standard sizes will be a big plus. This is why I sold my g6v2.
