The best one is whichever one YOU like best. I have owned and shot Heym (375 H&H), Chapius (9.3x74), and Merkel (470NE). Tried a Kreighof but don't think I would ever adapt to the cocking device but they are fine rifles. My favorite was the Heym followed closely by the Chapius. If I were going to buy another light double (read 9.3x74) it would without a doubt be a Chapius. Short ,light, QUICK, and built very nicely with good quality and I really like the beavertail forearm. For a heavy I prefer the Merkel as the most cost effective purchase. But in the final analysis it's absolutely YOUR choice that counts. It's like which do you like best chocolate or vanilla or coke or pepsi. I can't tell YOU what to like so I can't tell you what is the BEST buy. I currently own only the Merkel as all my medium's are bolt guns.
