IMHO, there is not much difference between the sexes, but there is quite a bit of difference between breeds. Choose a hunting companion for the job you have in mind, and remember that the hunting season only lasts a few months and the time they spend with you and your family goes 365/year. A great dog on the hunt sometimes causes serious troubles at home. And vice versa.
Also realize that very few dogs are "all-around-just-right-for-feathers-family-fur". I am a veterinarian and have pretty much seen one of every breed that had a nose find a dead bird. Lots of funny stories, including lap dogs, sight hounds, bulldogs, farm collies, etc.
I have purposely owned sporting breed dogs because they are very trainable, either male or female, and it is up to the owner to train dogs. Those that have great hunting genes are desireable, but you don't know until they are tried in the field. If they are just so-so on game, get 'em neutered and solve many problems. That is still a measure to consider unless you are planning to be very serious about the breeding business. Both sexes have "urges" and the timing may be inconvenient, like was mentioned above....females twice a year, males all the time.
The AKC has a great book about all the different breeds, and Google may have excerpts from that volume, but to them (AKC), all kinds of praise is heaped on every purebred.
If you are buying some rare breed for big bucks you may want to see the parents work in your hunting situation before you invest.
