Other than being in the same caliber (7x57), the two rifles you're considering are worlds apart in appeal, quality and "looks"... not to mention "pride-of-ownership"!
For many, many years, I lusted after a Ruger #1 International with its short, quick-handling overall length (just 36"), 20-inch barrel and Mannlicher-style stock. And so, a few years ago, I finally gave in to my "desires" and bought the RSI in 7x57... and never looked back.
To complete the "package", I had my gunsmith install a German-made Kepplinger single-set trigger in the little RSI and I am
completely and
totally satisfied with what I consider the finest looking single shot rifle on the market.
I also found the little Mannlicher-stocked RSI to be very accurate AS LONG AS YOU LET THE BARREL COOL DOWN AFTER
EACH SHOT.
I strongly urge you to buy the Ruger... however, it's gonna be your rifle, therefore it's your "call".
Strength & Honor...
