My friends primarily use Hertz and they say
they have had few problems with the company.
(I always remind them to get those miles whenever they rent!!! Even if it's only a few.)

I don't drive too much on trips (I've become
a master of Mass transit on four continents,
it's also a great way to meet people.) BUT
I like to add my name to the list of those
wanting separate entries for the car rental
firms: Alamo, Budget, Hertz, Avis, Dollar,
National and any other that has a program.
