The P-01 is a terrific gun, as are all the CZs. Get off the fence and get one. What are you waiting for?
To me the P-01's appeal is largely rooted in its alloy frame. A little lighter while sacrificing nothing.
Omega system? Personally I want absolutely nothing to do with safeties. No one is going to convince me otherwise, and I won't attempt to convince others if they're of the opposite mindset. So get the one you want, because it's unlikely you're going to switch back and forth yourself.
Of course if you plan to occasionally lend the gun to someone whose preference is different than yours, that's another matter.
Urban Grey? To each his own (again) but one thing I did not consider was how easily grey can begin to look dirty. Of course black gets just as dirty, you just don't see it. Grey is certainly a nice color though.
Trigger? Don't really how they compare to one another, but if you want a significant trigger improvement you're going to want to send it to CGW anyway
(or buy one from them).
To wrap it all up I'd lean in favor of your first choice. Find a good price and
grab one. Think about factory night sights if you can find one already so equipped. Having more $ than brains I wound up sending mine to CZ for a retrofit. They did a great job.
Oh I forgot to mention the suppressor option (thank Eastman for reminding me). Aftermarket threaded barrels are hard to come by.
