We had pergo good stuff easy to use. But water under it and your done for. The first floor we put in then that one got ruined by a backed up drain. That was going to be replaced with engineered hardwood. But when the flooring guys opened the boxes they planks were so warped it was not funny. Took it back HD gave us what we wanted. We went with pre-finished hardwood for our raised foyer and A Dupont laminate for the rest of the down satires. People make comments about how good our HARDWOOD looks all the time. Then I tell them it is laminate and they are blown away. I have 4 cats and a dog who love to run and play in the house. With the animals and the 2 kids the laminate is holding up great. The hardwood does not it has dented and gets scratched easy. Plus one joint pulled apart and now collects dirt.
I like laminate because you don't have to strip and refinish ever. The bad thing is if the floor is not level your going to have a hallow sound in places. If you have wood subfloor I would go with 1 of three things. Bamboo, Cork, or heated tile. There is no sweeter thing than getting up in the morning and walking down stairs on a cold winter morning to have your bare feet warmed gently by your warm tile.

Both cork and bamboo are green building products. Hell you can't kill bamboo I know I am trying and have been for 4 years. I spray it once a month with roundup ground clear and it still keeps coming back. Cork is also very green as it is made from the bark of a tree and grows back fast I believe.
