Hmm, my biggest concern was if the keys felt a little bit better on the filco. I'm assuming not because they use the same exact brown switches and costar stabilizers. I believe both keycaps are abs as well so there isn't any really difference at all besides the style. I gotta say though, the filco would look really nice with some lavender wasd keys and a red esc key.
Also yea, I noticed that the people at max keyboard are pretty fast to respond too. That's definitely a selling point especially since they are in the US too.
