+1 engineered for concrete slab install. Another benefit is that it comes pre-finished from factory so the install is quicker and less dusty/messy/toxic. Unlike laminate a quality engineered wood floor can be refinished 2-3 times in it's life - though not as many times as a real hardwood of course.

If my home had a wood subfloor I would probably go with real (3/4") T&G wood floor. Being that I am in Cali and we have concrete slabs (no basements) I went with engineered. No complaints at all.
