Compare the receivers and bolts of CZ and Savage. Side by side, it's easy to see the CZ's are bigger and more robust. Design and machining of the CZ bolt is better quality, and so easy to dismantle for cleaning. Even aesthetically, the CZ looks prettier.
And this is a big one for me; the CZ bolt and firing pin design allows safe dry firing without damage to firing pin and breech. When Shane at Reliable Gun explained that to me, I was very impressed and the price difference between CZ and Savage became moot.
I still have a Savage Mk2F and a Mk1GY as both are accurate and mostly used to teach new shooters.
