If you are talking muzzleloader the 50 is best .If you are talking cartridge the 44 mag is far and away the best as they are the ouly inherantly accurate one widely available. If you must choose between 32 and 38 a lot depends on the distance and such normally the 38 would be best.I use a contender 44Mag for long range target and some deer hunting also wild boar when its not practical to use a muzzleloader. I believe that the Encore has the stronger action my contender predates the Encore if I was buying now I would get the Encore. Lee
