Stop in at a gun store, and compare them side by side.
If somebdy hadn't told you they were based from the same design, you prolly wouldn't even find any similarities.
The CZ97 is in another class. Fit, finish, execution, all better by an order of magnatude.
IMHO, the CZ97 is the best example of a CZ currently available, save possibly for a P01, which I haven't examined personally.
