I own both the Beretta and the CZ... An M9A3, and a 75...
If you are familiar with shooting a 226, I can explain the differences between all three and hopefully give you a good overall picture for your choice.
Shooting experience:
I like to compare the difference between them with an analogy to cars...
The 226 under recoil, its kind of like an old Cadillac when it hits a pothole, smooth, and a little "floaty". Its easy to control, and smooth as butter, but it doesn't feel as responsive. Though, I can still shoot it well, even at faster fire rates, but it requires more effort in recoil management to shoot fast.
Under recoil a CZ75 feels more like a sports car hitting a pothole. You feel the recoil a bit more, but it feels more responsive overall. Very flat shooting, with easy recoil management. It does shoot smooth, but is a bit more abrupt. Because of that responsive feel, its easy to shoot quickly.
The 92, or in my case, the M9A3... Is between those two... Like a modern luxury car over a rough road. Its smooth, but not floaty. It is really fairly middle of the road between the CZ and Sig, but I would say it leans closer to the 226 side of things.
Feel in hand:
Both the Beretta and CZ are comfortable, but different in various ways. For me, the CZ feels the best in hand, and I recommend the rubber grips, not the plastic ones. The factory rubber grips are my favorite... Though the aluminum grips are nice two, if they are checkered well.
Both have long DA trigger reach. There may be a bit of difference in how long the reach is, but it is not huge. My Beretta having the Vertec frame, does reduce the reach, and is the shortest of them. A standard frame makes them more even.
The slide stop is easier to use in the Beretta, but the safety is better in the CZ. I also like how the CZ safety works more. It can not be activated in DA mode, only SA mode, so no risk of it being activated by accident in DA mode. But... No decock function, so if you want to use it as a DA/SA rather than SA cocked and locked... You must manually lower the hammer.
You can get the decocker model, and that is the best for defense use I think, unless cocked and locked is how you want to go. Some feel the decocker detracts from the trigger feel a bit though. (For defense, I would recommend the decocker with the Beretta as well. I do think the new conversion kit works with all 92s, so thats an option)
Trigger:
The Beretta trigger is better out of the box by far... Now, I have never fired one with the polymer trigger they use on the standard 92, that may affect things. Beretta does offer a kit to replace the poly components with steel though.
My M9A3 came with the reduced weight hammer spring, which is called a "D" spring, I believe. So the trigger pull is lighter than other 92 pattern pistols out of the box.
That said, a polished CZ75 trigger, with a tweaked sear to reduce the hammer camming, and a lighter weight hammer spring... (I have an 18# rather than the factory 22#. (I think its 22# factory anyway) Is a very nice trigger, being a little smoother than my Beretta, and a little lighter as well.
Now, spending a little money on a new hammer and sear set from Cajun Gun Works, along with the lighter spring and some polishing of the moving parts... Well, that is a fantastic trigger. I believe it is about $300 plus shipping for them to do the work for their Defense/carry package. Gives you a DA pull of 8lb and a SA of 3.5lb, with reduced DA trigger reach... They sell the parts in a kit for home install as well.
So out of the box, the Beretta is the best trigger hands down. The CZ will smooth out after a few hundred rounds or so, but not be quite as good as the Beretta when both are broken in.
If you are willing to put in a little work polishing and swap the hammer spring, the CZ will pull ahead. Put a bit more effort and money into it, and it will be a very nice trigger. With competent professional work, it is one of the best... There is a reason they are popular in competition the world over.
Final thoughts:
I really like both the CZ and the Beretta... But I really like the tighter responsive feel of the CZ when shooting it more. Also, the ergos, are a little bit better for me.
The SP-01 version is the best shooting version of the 75 I think. A little extra weight up front, keeps the muzzle down a little more. The longer beavertail also helps as well. I really like how they shoot, it is my favorite hammer fired pistol. Modern striker pistols can offer a similar tight feel, but the recoil is a bit stiffer with more muzzle rise, due to less weight... So I would say the CZ, especially the SP-01, shoot a bit flatter.
In the end, its up to you, what feels right in your hands, and what kind of shooting experience you want.
