Zimm sets -- ATAK vs. Mirage?

Anybody out there crazy enough to regularly use the resin zimm sets? I notice that not one but TWO Polish companies, ATAK and Mirage, make the stuff. I've used the Mirage set and it's not bad but the molding makes the resin a little thicker than I would have liked in some spots, making it difficult to set the zim around corners on the turret, etc.

Can anyone here compare and contrast the ATAK and the Mirage zimm sets? Thanks.
