I mean, it really comes down to you weighing preference versus patience.
Filcos are a tad harder to come by now. The only two places I know where you can order them online are armygroup and keyboardco. You'll be paying quite a bit in shipping if you order from either.
Das has a glossy finish on it which makes it prone to smudging and fingerprints. The design is also a little different than the Filcos and Leopolds. If this doesn't bother you too much and you want one 'right now' you might as well just order it.
Leopolds are, essentially, a Filco clone aren't they? If you were waiting for them to come because you like the design (which I think you might be, because you could have ordered a Das whenever if you were interested) you might as well try and tough it out to get what you wanted. Or you could order a Filco if you don't mind spending a little more for shipping.
