I have no personal experience with CZ rifles. I have only heard good about them though. Most of the people who mention them on this forum, say they are exceptionally accurate. They may be made here in the U.S.?(CZ of America) Not sure. If so, do the royalties stay in America? Too much for most folks to worry about.
Savage I have experience with. I have owned three; two were 110FP's (7mmRM & .223) and both of them produced sub 1/2" groups with handloads. I now own a 112BVSS in .300WinMag and couldn't be happier. I'm getting .3" groups from it regularly with handloaded 180gn Ballistic Tips, right at 3100fps.
Also, with the Savage, it is possible to change calibers within a few minutes. Sharp Shooters Supplies (Sharp Shooter Supply - The Savage Specialists
) sells barrels, barrel wrenches, stocks, bolts, bolt parts (heads, handles, etc.). Pretty much everything you need to change calibers. Check it out.
I won't suggest you get one or the other. I'm not because both are good rifles, each with their own qualities. Both capable or terrific accuracy with the right loads, good glass and the right "nut" behind the trigger.
I tell ya what I'd do....buy one each! JohnnyK.
