I have owned 6 different hm2 rifles. 1 Savage mkll, 1 Marlin 917, 1 CZ 452 and currently 1 TC R55 Sportster, 1 Custom Remington 581 with an Anschutz 1502 barrel and 1 Summit with an ER Shaw Barrel and Custom stock. I would say my current 3 are by far my favorites with the CZ coming in 4th and the Marlin 5th leaving the Savage last. When it comes to accuracy, my 581 is probably the best, Summit, TC and others all close in.
Biggest differences are probably feel, asthetics, trigger and fit. Accuracy overall not a lot different from first to last but I have a hard time leaving them alone until they shoot acceptably. Cost wise you can almost reverse the order with the exception maybe of the Summit being the most expensive but I build my own rifles and most stocks any more so costs will vary depending on what you do. If your leaving it factory, for strictly a beat around utility type gun you won't go wrong with the Savage or Marlin. If you are into quality, a custom, the Anschutz or Summit but also there is the Sako and a few others. CZ is the happy medium. I don't think I have helped you at all.
