I think it depends what you like. I look at cases, pick out a load that I like style-wise, then read reviews and pick the one that gets the best reviews (well, ideally. I can't find a case I'm 100% happy with, but never mind).
I assume, as you've picked out Antec and Coolermaster, you like the 'different' styling, like that on the HAF range and Dark Series?
I'd take a look at the following:
-NZXT Phantom
-Coolermaster HAF-932 (if you must)
-Antec Dark Fleet DF85 (if styling really isn't a problem)
-Lian Li PC-P50B
-Coolermaster Storm Sniper
-Silverstone RV02 (great aircooling ability, and the CPUs doesn't get the GPU's heat)
-Antec P183
-Fractal Design R3 (bit cheaper)
-Lian Li PC-B25FB
-Zalman MS1000-HS2
I seem to remember that the Fractal XL had issues in the cooling department - not enough fans for such a large case.
