I'd recommend the QFR; cheaper than the Filco and just as solid, the caps are better as well, although doesn't matter that much if you're looking to replace them.
Doesn't have backlight though, but I don't really see how backlight can be a make-or-break point for a purchase. It is, however, another part of the board that can go wrong.
Edit: To clarify a bit; I have both a QFR and two Filcos and right now I see no reason to recommend the more expensive Filco over a QFR, although the branding on the QFR isn't really all that pretty.
The QFR also has media keys, which is nice, and I really like having the Lock LEDs under the cap instead of separate.
