Great choice! My friend loves Berners. :)
Male or Female is really a personal choice. I prefer male dogs because I don't like having to deal with their first heat before getting them spayed. (Of course you can get them spayed before hand, but I prefer to wait until after they've at least had their first heat.) And I think there's a slight personality difference in female vs. male dogs if they're not fixed due to hormones. Like most unspayed female dogs I've met have been really independent and sort of 'self-centered' almost, haha. While males, from my experience, are more affectionate and want to be around you more which I like. Of course i think it pretty much evens out if the dog is fixed. I haven't noticed a huge difference in behavior from unneutered to neutered male dogs, but I've noticed a difference in spayed vs. unspayed female dogs. And of course some people don't like male dogs because they're uncomfortable seeing their 'boy-parts', and if they're not fixed then, depending on the dog, you might have to deal with a lot of marking (peeing on everything) and humping. I never had to deal with that with any male dog I've lived with, except during the 5-7 or so month old period where they're really hormonal. Which is why I'm getting my Golden Retriever neutered at 6 months to avoid that entire situation, haha. But my parent's dog isn't neutered and he only went through a humping stage at about 5 or 6 months old and then it was done with and never revisited and he's never had a problem with marking.
So it all depends on the individual dog, and so it kind of depends on your own personal preference.
