When it comes to choosing weapons it doesn't boil down to whats the better or most accurate any more
All rifle manufacturers are competeing very well against each other now.
A good shooter can achieve good accuracy with most any weapon he chooses, he may have to try different ammo's
and adjust his sites a few times but in the long run he should be able to become a safe shooter and hunting accurate.
I think a savage is a very good weapon but that doesn't mean it's better than the other rifle makers.
The rifle you choose should be the one you're most comfortable with, Personally, If I were buying a .17 HMR
I'd get the Ruger K77/17, that's my opinion but if your final choices are between the Marlin or Savage I'd opt for the savage too..
I hope this helps. Good Luck to you on which ever you choose.
