Hardwood in the Dining Room (DR), sheet or tiled vinyl in the kitchen.
Cons - Nails in a nailed floor MAY work loose depending on the 'soundness' of the floor it's installed over. Glued floors float. I don't like floating floors mainly because there's a 'hollow sound' when you walk on them (since they aren't 'nailed down'.) They feel nice and soft but that's about it. Oh, you can't refinish a glued floor with any type of mechanical sander. (They need to be nailed or stapled.) And as a personal preference, I don't like stapled 'anything' to the floor.
Pros - Nailed flooring is as Steve: stated. Glued flooring is easy to replace which is what you have to do when it 'wears out'. The same for floating floors.
I'm sure there's more but it escapes me at the moment. My best to ya and hope this helps.
