To be really pedantic, there was an Air Match CU400, though it is little known.
The draft feels very right.
My experience is limited to the FAS, FWB80, Gamo, and Diana 6G/M. I'm not a proper 10M shooter, but from my perspective the FWB is the best built with the best track record, but I do not myself shoot that well with it. The FAS is the cutest to play with, but too short and light. The Gamo - mine is an early one with a good trigger - is a good gun for not much money, but obviously not top drawer. I shoot best with a 6M.
On which basis, the 46M may be the best choice. I hear nothing but good about them. But going back to a Diana 6 and using it to get back into the sport while trying other people's guns might not be a bad option. Just ensure it has been properly resealed, or buy cheap and get it done.
