Hertz - Hertz at ATL

I am going to be renting a standard size car as a #1 club gold member every Monday morning returning every Thursday evening for the next 5 months. I am debating going with Avis or Hertz and I wondered what peoples experiences were in the ATL location. I have always had very good luck with upgrades especially in Atlanta getting an Azera the last time I was in town.
Thoughts? Thanks!!

Rented in Atlanta a couple Saturdays ago. They were behind in their gold cars, everybody had to go into the service counter, and wait a few minutes for them to assign a car. Not a huge deal, but still a bit of a pain. Returns quick and easy. Got a class upgrade and Sirrus, but I think that's only because that was the next car they had ready more then anything else.

Hertz and Avis at ATL are pretty similar. Both of them occasionally have computer troubles. Both give upgrades at a similar frequency. I think Hertz as a Gold or 5* is slightly better than Avis as a Preferred or First, but not enough to make a real difference. If the rate is the same I would go with Hertz just because it has a covered lot in the event of rain.
