If you don't mind the branding; I'd say a CM QFR. It's cheaper than the Filco and, so far, I can't really see why you'd get a Filco over a QFR considering the cost.
Filco is still a solid and safe choice, looks nice as well. If you want to play it safe and don't mind spending some cash; Filco. If you're looking for bang for your buck and don't mind the CM branding; go for the QFR.
I don't have any other brands so I can't say much about them, except that the stabilizers on Leopolds might not be for everyone and the Deck font is ugly as fudge.
