Fair and balanced review is what I want to give.
Cheap prices, good cars, two shuttle busses to fox- not with other car rentals, this second shuttle feels like a pain but only adds 10 minutes to your car rental trip, very few employees when I checked in so it was a very very long line however please note I've had similar problems with the name brand car rentals at the main rental terminal, staff was polite helpful and not high pressure.
If you are flying in with small children or very early/very late this second shuttle seems very difficult but it really is just one more step in a long travel process no matter what you do. For me cost was SO LOW it was worth it.
