Likely you'll get lots of advice from folks who like the platform, but I didn't. Here's my story.
I had a CZ75 Pcr for a few months before I decided to sell it. It felt good, was reliable, and was relatively compact (the size of a Glock G19 and Browning Hi-Power) but I felt it needed to be a project pistol to smooth off some of its (figuratively) rough edges. At some point I decided its great "feel" just wasn't enough.
I would disagree with folks who say it has the same quality as a Sig, however, unless you're talking about just simple reliability. Compared to a Sig, the double action trigger reach is longer and rougher, and the single action weight is pretty good at 5.5 pounds, but was also a bit rough. I found the stock sights a little hard to see (old eyes, I guess) and there are few aftermarket choices for this. These things take money or time to improve.
Also, it's just taste, but I didn't care for the baked-on finish, or the "busyness" of all the printing/details (huge, ugly print) on the slide. The slide is inset to the rails rather than outside as on most pistols, so the forward cocking serrations seemed pretty useless to me - it's difficult to rack it from the front serrations with on 3/4" of purchase on the slide and that heavy recoil spring while keeping your fingers out of the bullet path.
Finally, I shoot with my thumbs up, so the slide release was in an awkward position for me - it threatened to be activated on every shot, but was too far forward to be useful as a slide release with my thumb for a new magazine.
Again, I found it reliable with real advantages in overall height (compared to a Sig) and feel. It did need extra gunsmithing, and while I looked into doing it myself, it looked too complicated for me. Parts cost was $90 for a hammer for the SA issues, $90 for the disconnector that would have allowed a shorter double action pull, about the same for the short reset, $80 for sights I could see, plus costs to install all of these things, plus maybe another $200 for smoothing the action (or lots and lots of firing to accomplish the same thing). Getting it all done at the same time was $500 by a competent smith. Get it all done and you have more in it than you would a Sig with some advantages over a Sig, but you better plan on keeping it forever, because you can't sell a worked over CZ at a Sig price. FWIW.
