Depends on your needs,
I love max and will take it over both Herrett or B&D, because I can use carbide dies, no case forming and the Max is much better with cast bullets, especially heavy ones because you don't have to worry about deep seating below the shoulder as you do on herret and especially so on short neck of B&D. If you are only going to shoot pistol bullets, the B&D is ok, efficient and powerful, but you will run into troubles with rifle bullets and deep seating again. Given my druthers, I'd strongly recommend the Max over both others. I still have a Herrett and sold off the B&D, just for your reference.
