Quick pickup and excellent service attitude.

Excellent

It's just okay. Avis and Budget seem pretty much the same, always using tricks to make you spend more on their extra insurance or options like returning an empty fuel tank. Even if you decline, they may sneak it in while you're not paying attention. They'll claim the agreement was emailed to you in digital form. Make sure to demand a paper copy after signing electronically and double-check it immediately!

Acceptable, but don't expect too much from the service in the US.

For self-driving in other European countries or places where you understand the language, any car rental company is fine. However, for self-driving in the US, I found AVIS to be the most reliable, though Hertz is also good but tends to be more expensive. Compared to Hertz, AVIS offers better value for money. The cars are new and come with Easypass, so you don't need to rent it separately. Some companies seem cheap at first, but when you add the Easypass rental and other hidden fees, the total cost is much higher than AVIS. The return process is very simple, and the service is very patient. I'll definitely choose them again in the future.
