Dollar for value the Z5 Omega is about as good as it gets. It will shoot with any of them it takes a bit longer and is a bit more involved to clean than the Triumph.
A Triumph is one of the most accurate muzzle loaders and easier to clean by far than most.There are some other good ones around like Knight but the fact they shut down bothers me and the Savage which is the smokeless one. It does pay to shoulder some and get one that fits. You might check a few of the regular hunting pages the professionals have also. Lee
