What are you looking for; fancy or accurate?
CZ has made quite a few ""fancy model" guns with upgraded stocks etc, but they are all basically a 452 or 455. Which is best is strictly a personal observation.
If you are looking for the most accurate CZ: How good of a shooter are you? How much are you willing to pay for ammunition and aftermarket parts? How much time are you willing to spend practicing? The standard 452 or 455 will out shoot most owners. They all share the same model action, trigger and bolt. Some models have target triggers or a different barrel. Stock design range from the hogback which is better suited for open sight shooting to straight back for scopes. Then there are speciality stocks like the thumb hole or composite precision stock.
