Floating floor verses glued
Glue down wood flooring is what they refer to as "engineered flooring". That's a fancy way of saying it's oak plywood that's been tongue and grooved. Wood expands and contracts with the width of the board about 100 times more than it changes in length. By constructing "engineered flooring" so that the grain changes direction you make it much more stable than solid wood when it comes to expansion and contraction.
You should be looking at appearance when deciding which to go with. Both will work. Laminate is going to be more scratch resistant. Engineered flooring is real wood.
