We used the pergo brand in a light oak color that has all of the wood grain in it and I love it. Everyone I tell it's per go says it looks like wood. It does have to be mopped/swiffered frequently, but it's so easy to do and I love that it is so much cleaner than carpet. All that dust was still in the fibers of the old carpet, you just couldn't see it. We did our family room, office, upstairs hallway and 3 bedrooms. My room still has carpet and I'm dying to replace it but can't do it yet. We got a close out on a discontinued color at HD (had to go to 4 or 5 stores to get enough) and got it at a great price. It's been 2 years now and it 's holding up beautifully.
I have real oak in my living room and dining room and honestly it looks good but the pergo looks just as good and is tougher.
