They're all corporate stores, so the policies are similar to what you experienced at the airport. Neighborhood store pricing can be better, especially for long rentals and/or one-ways where the airport taxes can really bite. But the number of cars is frequently smaller, and everyone must stop at the counter. If you order a specialty vehicle, they may have to request one from the airport.
Ex, If that minivan with 27k mi and smell of diapers is not to your liking, there's no Gold Booth with another 500 cars available to switch it out. But it could be substantially cheaper.
As you can see, satisfaction at an HLE is in part a matter of expectations.
