My CZ is a little .204 Ruger for rock-chuck shooting. Excellent value for the money! I'm getting 1/2 MOA groups with 35 grain Bergers at 3900+ fps. Really gets with the program.
Mine came from the factory with the detachable magazine that I've come to find very useful. Also a walking-varminter type barrel - not too heavy, but stout enough for precision shooting. The barrel was free floating. And the rifle has a very interesting set trigger. I didn't like it at first, but after using it for a while and making some fine shots on varmints, I decided I liked it.
I also liked the milled-in scope mount. Also liked the terrific little mini-mauser action. Good all-around rifle, of decent quality for a production piece. I don't have any experience with the other models, except for the little .17 HMR varmint model I bought for my youngest son. It's bordering on incredibly accurate and has been a hoot! Unless of course you want the ground-squirrel's opinion of the dastardly little .17 varmint blaster!
The safety works "backwards" from what we Americans have come to expect. Takes a little bit to get used to that.
