The **most-used, mainstream car rental brands** people actually book are **Enterprise**, **Hertz**, **Avis**, **Budget**, **National**, **Alamo**, **Dollar**, **Thrifty**, and **Sixt**.[3][8] If you want a practical shortlist, **Enterprise**, **Hertz**, and **Budget** are the safest first picks because they show up repeatedly in traveler discussions and booking inventory, while **Avis**, **National**, and **Alamo** are also widely used.[2][5][8] A simple way to choose among them: - **Enterprise**: often praised for service and consistency in traveler discussions.[5][6] - **Hertz**: a major brand that is widely available and commonly used.[3][7][8] - **Avis**: another major national option, commonly listed among the main rental brands.[2][3][8] - **Budget**: frequently recommended for lower prices and value.[2][4][8] - **National**: a common choice among business and frequent travelers, and part of the major-brand set.[5][8] - **Alamo**: widely used, especially for airport rentals and leisure travel.[8] - **Dollar** and **Thrifty**: often mentioned as budget-friendly options.[4][8] - **Sixt**: a major international brand that is also commonly used.[3][8] If you mean **best overall travel platforms or booking sites** rather than the rental companies themselves, the commonly used options in the results are **Expedia**, **Booking.com**, **Rentalcars**, **Kayak**, and **Skyscanner**.[1] If you want, I can also give you a **ranked “best by use case” list** — for example **cheapest**, **best for airport pickup**, **best for service**, or **best for luxury/EVs**.
