I just got done putting down laminate flooring in the kitchen and dining room in my new house last weekend so I know a bit about the stuff. I heard just the opposite of what you heard. I heard the Armstrong and other brands were not near as good as Pergo. I talked to several people that had Armstrong and all I got were complaints about the Armstrong. I have several friends in the carpentry business and they recommended Pergo out of all the laminate flooring brands. The Pergo was very, very easy to put down. We had about 300sq. ft. to put down and were done by 2:30 after getting started around 9:00. Pergo comes with the underlayment already attached and it seemed to work very well. The finished product looks awesome. Made a huge difference. I'm very satisfied with it at this point. There doesn't seem to be any shifting and I rarely hear a slight "pop" from the joints. We'll see how it holds up but for now, I'm happy with it.
