Like you, I was debating which to buy. I liked the Taurus safety/decocker on the frame instead of on the slide as with the Beretta. Then it was CZ 75B or CZ 75BD. I ordered the CZ 75 B with the safety. I understood the difference too late to change the order to the decocker. The CZ 75BD would have been $35 more. Not enough difference to influence my decision. The CZ 75 will be a range/home defense weapon. No concealed carry. I would have preferred being able to decock a loaded weapon instead of locking one. It just my preference. I don't like the fact that the hammer must be cocked before applying the safety. Again, my preference. I'll learn how to decock the CZ 75B manually.
I wanted an all steel handgun. There were too many stories about the quality of the Taurus steel. I didn't want to take that chance. I preferred the CZ quality and reliability. That was the major reason for my choice. I hope you are satisfied with your decision. That's what counts.
