So 18 years ago I bought a steel bike, a friend already had a TI Seven for a couple of years, and another friend bought a Trek One carbon frame.

The Ti bike is his sole form of transportation, so it has the most miles. Probably 200 miles a week average. Still going strong, despite at least 4 serious crashes requiring hospitalization and being hit twice by a car. Frame did not take any damage above a little road rash.

My steel frame is still going strong, one minor ding.

The Trek One is long since dead.
