Well, given the CMstorm is roughly half the cost of the filco, at roughly the same quality, I say it's a great deal. I bought my CMstorm in blues for something like $64 not too long ago, so if you are willing to wait for a week or two, you can get a really good deal. I've never sold a CMstorm, but I consider ~$60 to be an excellent deal for a mechanical keyboard, even in lightly-used condition. I'd still recommend checking the classifieds, but you really can't go wrong there.
So, if you can "put up with" the branding and logos on the CMstorm, I'd say it's your best option by far. Keep in mind, however, I've not used a filco in person, as I consider them to be a little too overpriced for what you get.
As far a "brand loyalty" goes, I'm more loyal to the OEM (costar) than any "brand" that sells keyboards. That's just my personal position, though.
