There's good and bad in both breeds. My suggestion is to pick a color, then research bloodlines and find what suits you.
Best advice your gonna get!
I've always hunted Texas breed dogs but tried plenty of Catahoulas back in the day along with just about everything else. I got to the point of hating the breed and vowed never to waist my time with them again! The only cat I ever kept was double registered. Pretty as they come but couldnt find his own a$$ in the woods if it was on fire! No hunt to him at all but one of the best catch dogs I've ever owned.
After hunting with two different guys the past few years that owned some dang good ones and seeing successful hog hunters using them on this web site I have come to realize that I just never got ahold of the right blood!
