the CZ has two pure Mauser 98 features which the Ruger doesn't, the 'C-ring' breeching, and the extractor with the under-cut which prevents the extractor hook from jumping out and letting go of a stuck case.
The Ruger has probably the simplest and most robust trigger and safety system around, though to my fingers, the safety wing is a little small.
The CZ has what is probably the most complicated trigger system on a commercial bolt action, though they seem to be reliable and some people (not me) really like the single set feature.
I also like the all steel sights and front band on the Ruger, rather than the alloy rear and ramp on the medium CZs.
Having said all that, as bigsqueeze said, none of the differences will likely affect the outcome of a hunt.
