I own a newer BE (manufactured 1/2000), and a military CZ-75B in polymer finish. The BE is a few ounces heavier, has a full length frame, and polygonal rifling. The BE has a slide mounted decocker/safety (like Beretta's), while the CZ "B" model has a frame mounted safety w/o decocker. To decock the CZ, you must manually drop the hammer. Buy the "BD" model of CZ if you want a decocker.
I like both guns very much, but have found the Eagle to be slightly more accurate, and more comfortable to shoot. In fact, the Eagle is quickly becoming my favorite "shooter". I still think the CZ is a great gun, and I hope to add a CZ-75BD (nickel), CZ-83, and CZ-97 to my collection, sometime in the future.
You really can't go wrong with either gun, but personally, I give the Eagle a slight edge.
