Of those, I'd get the CZ75
1911s are nice, but they are made to be 45s, and 45s just kick more. 1911s are not even the lightest kicking 45s. I think HKs are. The PX4 in 45 was very nice too, but it has the plastic thing going for it like the Glock does. It just doesn't encourage emotional bonding like metal does to me.
CZs are super nice. One of the best grip shapes ever. Bad DA triggers though. Fans say they smooth up with dry firing and use. The slide's a little harder to grip, since it runs inside the frame instead of outside. (this is supposed to make them more accurate) I'd buy one myself if I were in the market for another nine.
But earlier comments on the Hi-Power are right on. It is the perfect mix of a 1911 (single action, classic Browning design) and CZ75. (super comfortable grip, easy recoil) With a Hogue grip, it is even more comfortable than the CZ.
Saying generically that 1911 triggers are better is not really fair. They can be fantastic, but they can also be pretty heavy. The trigger on my Hi Power, even with the magazine disconnect still functional, is better (lighter) than that of my entry level 1911. The recoil is 1/2. The take-down is much easier and faster. The 1911's take-down is not hard, there are just a lot more steps to it.
I bought a Glock once, a 34, the modern competition 9mm. I'd wanted one all my life. But in the end, it was just pretty blah, and I sold it for something metal.
Here are my two guns that were talked about here, a Charles Daly Hi-Power in 9mm and a Para GI Expert in 1911:
Not particularly good shooting on my part, but there you have it.
Pre-Hogue grips:
If you have no loyalties, 9mm 1911s are a real joy to shoot. Nobody seems to want them, so you might be able to make a good deal on them. 38 Super is out, unless you hand-load or are pretty rich.
