I think highly of both companies, although my use of each has varied dramatically depending on my circumstances. When I owned a car, and lived in the suburbs, Enterprise was great because I already had insurance coverage. When I needed to rent from them because my car was being repaired, they would come and pick me, which was great. In every location I've been too, the staff has been very friendly and helpful--it was no surprise to read that management practices at Enterprise had informed work on Net Promotor Scores. Now that I live in a city, and do not own a car, ZipCar is fantastic. The annual insurance fee is less than a day's insurance cost at a traditional car rental company. I can get chores done in just a couple of hours, so renting by the hour is incredibly attractive, especially given the abundance available in my neighborhood. I would likely pass by over 20 different Zipcars on the 10 minute walk to the nearest Enterprise outlet. Zipcar employees are also incredibly friendly and proactively helpful on the phone. Sometimes when companies have different policies and products, it's because they are targeting different segments of the market, not because one is better than the other.
