Triggers are a personal preference item, like so many things. I have a "few" CZ's both with safeties and decockers as well as one with the Omega trigger. I run 9mm pistols, sometimes with a Kadet Kit. My Kadet kit works with my old 75B, my P-01, my 75B Omega but not with my P-07.
I have no issues with the Omega trigger. It works fine for me, but then I cut my CZ teeth some years back on a old fashion 75B before anyone even dreamed of an Omega trigger. The Omega trigger is a "simpler design" as they say. Fewer parts, cheaper to build, etc. It also, to me and many others, has a better pull compared to the factory trigger on the older design. Yes, a custom shop can work wonders on your CZ non-Omega trigger. If you want to let go some of your money and do that then by all means go for it. If you know you will never have trigger work done and just want a great shooing, reliable factory stock pistol, at least consider (try out) one of the Omega models. You may actually like it.
I know some here want nothing to do with the Omega, but you be the judge.
