Pergo.. we have it installed in our living, family, kitchen, hallways, and stairs. It is Prodigy, weathered wheat plank. LOVE IT!
We had it professionally installed.. cost a bundle.. the stairs were $80 each stair for labor... yowza!! It is easy care.. swiffer and mop with vinegar/water. Looks very good, sounds good and is standing up very well to dogs, kids, and heavy traffic.
I am a very picky woman.. very.... I like the look of the pergo.. I don't try to "fool" myself or anyone else to think it is hardwood. Most of the neighbors bring their dh or dw over to see the floors.. many have installed the pergo into their homes now.
We had hardwood floors in our old house. I will admit it looked nice... for a while. It was hard to upkeep, expensive to repair.
When I am retired, hardwood would be a good choice for me.
Tile is nice and cool but hard to stand on for extended periods.
Carpet is beautiful.. and my favorite floor covering. Just can't keep it clean enough to suit me with the kids and pets right now.
I think it is different strokes for different folks. oh... and I do believe you get what you pay for...
