I have only titled bitches. I tend to like tough dominant females that define the word "bitch".
They are not easy to find nor easy to live with. Most females do tend to be softer and more sensitive than the boys. Females can be as hard, as tough, and as aggressive as males they are just not as common. The problem I find with bitches is they tend to think too much so you need to be on your toes. Trialing a female in heat is a pain and some females don't track well, can get squirrely in protection (mine tend to get meaner) or overly sensitive when in heat.
Males are more reliable, bigger, and more powerful than females. They may not come into heat, but some males turn into absolute worthless idiots when they know there is a female in heat around. Males also seem to fit into a household with other dogs, especially females, better. A big powerful male can be harder to handle especially for a novice handler, they do tend to be more forgiving than most females, but also tend to have a bit more a of mind of their own.
I am currently working a male (along with 2 females) and there are things about him I like and things I don't. He has taken longer to come into himself than his sister (littermate) and is farther behind in training. He is very big so physically much harder to handle. Luckily he is not an idiot when the girls are in heat and he is very easy to live with. He is very impressive to watch, very hard to corrections and forgiving (which my girls are too) and has fantastic tracking ability. He can get a hair too focused on what he wants and at times not as willing.
I am not sure I will ever handle another male. I still like my nasty pain in the rear bitches (well, most of the time).
