My father installs and finishes hardwood floors for a living (for about 20 years now). I worked with him all thru high school and even now when he needs some help.
I've mainly installed Oak and Maple floors and the occasional pine. They hold up really well (except pine, it's a bit softer). I've never even heard of using Bamboo. Isn't bamboo rather soft? I wouldn't think it would hold up too well.
Bruce flooring and laminated, in general, sucks. It's easier and takes less time but you end up with a crappy floor. We've installed quite a few. Half the time the owner doesn't like it and has us sand it all down and refinish it.
If it was my house, I would avoid Bruce. Bamboo, well I've never used it. Might be good! I would recommend Oak. It's nice and hard, ages well, and is quite pretty.
Good luck and congrats on the new house.
