I did pergo at my old house since it was my first home and wasn't worth putting in anything nicer. It's held up great to roommates, pets, and now tenants. Very worry free and easy to install. But, how "real" it looks depends on the type you get and how good you install it. Making sure to not line up seems, no gaps, etc.

In our house now, we have the pergo too. The prior owners put it in and I don't mind it. Again, it's very worry free and I like headache free stuff. If I ever had to replace it, I'd find another hard surface of some kind to put in. I like carpet in the bedrooms but prefer non porous flooring everywhere else. This house would allow me to upgrade the flooring a bit and get my money back out of it.

Dark floors=paw prints, foot prints, dirt, etc showing.

Lighter floors=hides a lot more.
