I own a Filco and a QFR. Both are TKL and with mx red switches. The filco was purchased only five days after I received the QFR, because I want to have the menu button on my keyboard so I can remap this key with softwares. The filco is one of few keyboards that come with the standardized us layout with no Fn keys, which means that every key stroke sends key code to the PC. Comparing to QFR, the typing experience is slight better, and I definitely enjoy typing with Filco more. Fiilco is over-priced, but the first moment that I type on it after unboxing, I knew this would be my favorite keyboard.
Comparing to QFR, filco offers me
(1) a better plastic chassis;
(2) more elegant keycaps;
(3) a menu button instead of a Fn button.
However, I do wish the USB cable on filco can be detached.
