Blued finishes are the most rust-prone of finishes and easily show scratches and finger marks. You find yourself constantly wiping them down.
At the moment I own an 85 Combat (satin nickel), 75B in .40 (polycoat) and a 75 Compact (satin nicke). I have a Kadet Kit. I have owned a 75B Mil, several 75 pre-Bs, several 85 Combats (one high gloss blue), several 75 compacts, a CZ-40B, a CZ-97B, and a CZ-100. Most of them have been sold to forum members, over time. I presently also have a very nice EAA Witness Sport Long Slide (in .45) with a 10mm top end, a highly customized AT 84S, a standard AT-84S, and a Sphinx 2000 compact. (All but the CZ-100 based on the 75 design.) I don't, as a rule, have more than one of a kind (of a particular model) unless I pick one up in trade for later trade.
I like CZs and CZ pattern guns, but I also like other guns, too, and have a number of them, too. I shot my SIG GSR (1911) in our last IDPA match this past Friday, and frequently shoot a Glock 34 and Browning HiPower in those matches, too.
