I have both a G19 (gen4) and P-10C. From this shooters perspective, the P-10C is easier to shoot well (ergos, trigger, low bore axis = flatter shooting) - and silly accurate. I can, and do , shoot the G19 well, but it is not as enjoyable and "easy" to shoot. If you are looking to highly "accessorize" your pistol, as others noted, glock aftermarket support is enormous, far surpassing CZ. So, it depends on what you are looking to do with your pistol, and what you like. For pure "shootability", for me it's the CZ (and I have repair parts for it and you can find good holsters for it as well). I have both, and am confident in my abilities with both, but in most situations I'd grab the CZ first. I know this is GT, but buy what you want.
