witch is better

That is like which is better boxers or briefs? It is a matter of personal preference. With each bread there are pros and cons. Within each bread there are good and bad dogs.

My opinion pits start quicker and take less training. But I do not like their style. That does not mean anything except I do not want one. It seems AB require patients. They catch later and take more effort to train. But this is only based on why I made my choice. If all you want is a dog to put on a chain and take hunting then pick based on catching style you like. If you make the dogs part of your life then the personality matters. My dogs take turns riding with me when I run errands and play with my kids. I went with an AB cross because it fit better with me. Go hunt with some and watch them and decide what you like based on how the dog fits you and your style.
