My father has both: a CZ 75B Stainless and a CZ 75D Compact (P-01). The P-01 has a decocker, the 75B an ambi safety. If you are going to carry, the P-01 is better and it is also a little more accurate, at least for me. The 75B Stainless is the best looking one. If you have medium hands the P-01 is just perfect. I've recently made a review of each gun, if you want to take a look.
Best regards, 5-SHOTS.
