Depends on the application really. The prefinished hardwood they are making now is fabulous. I would say, unless you are restoring a historic property, or have a reason to use unfinished, go with the prefinished. You wont have the mess, it will be done quickly, no fumes.

If they have been sanded recently, you might have a satin sheen in the polyurethane that was applied. If this is the case, all you have to do is re coat it with a semi gloss or gloss polyurethane.
