I prefer to have unfinished flooring installed since we can do it before moving in, but the wife likes the pre-finished as it will take less time and make less dust. I personally don't like the look of pre-finished with the beveled edges, but I could have lived with it had we found a house with it already installed. I know the finish on pre-finished is typically more durable than post finish, but I think it tends to be more "shiny" also, maybe not. Some brands of pre-finished supposedly have smaller bevels and thus don't show the lines as much, but until it's down on the floor, I don't think you can be sure of that.
I would try and set up some blower fans to exhaust air out of windows during the installation to try and cut down on the dust left in the house. There is a whole house attic fan in the home, but I wouldn't want to fill up the attic with sawdust !!
