Welcome to TFL !
I've owned/shot both the M70 Safari & the CZ-550 American Safari, and (sad to say) like the CZ better because it had a denser stockwood, and a 2nd recoil lug, about 5" ahead of the usual Mauser lug on the action.
The setable trigger on the CZ was nice, too.
Both makers install steel crossbolts in the stock - a wash.
On the minus side, CZ's require special rings, if one's to be scoped (I used a Leupold M8-2x); and the #/*&%\@ ^$ stoopid so-and-so's @ CZ mount the front sling QD stud on the forend ILO the barrel, which means relocation & hole-filling (on the forestock) to keep from tearing up the hand.
