That's more info than we had before... But you can look at the parts on your bike to get valuable information like the model names/numbers on derailleurs, for example.

Knowing the age of your bike and what came stock on the Tourmalet, it's a pretty safe bet your Peugeot is nicer than the Follis on Craigslist. The Peugeot is going to be a lighter bike with a nicer drivetrain. Better parts availability, too. And more serviceable since it doesn't have a cottered crankset like the older Follis.
