I have both the KUL and Varmilo. For just gaming, I would recommend the Varmilo. It is a bit more compact, has less to no ping (probably less empty space in case), and the Cherry stabilizers aren't mushy (I'm guessing they are pre-clipped??).
Also, it comes with thick PBT caps that thock really well, and feel very crisp and solid when gaming. (However, I still like ABS for the WASD cluster since it provides more friction than PBT and I like using a WASD cluster that is raised higher than the rest of the keys)
That being said, I actually like the KUL a bit better overall since it has more long term modding potential for me and a nicer finish, but for a pure, out-of-the-box gaming board, I have to recommend the Varmilo. Mine is actually my DEDICATED gaming board, now.
