'Our' comments are the same. 'We' have had mixed results.
Since you're already 'familiar' with what some folks have said, it's time for you to 'decide' or weight the +/- of Pergo based on how you're gonna use the room, the sub-floor, above/below grade, cost, repairability, added value, and so on. Really, if your findings are mixed, that's pretty much the way it is w/Pergo.
Personally, (which you didn't ask), I'm not a Pergo fan, no matter what the 'situation'. I'll leave it at that.
My best to ya and hope this helps.
