They're a step above in the US as well. I rent from them whenever possible. Their vehicle selection is relatively small, they have few outlets, and I can't say they have the best (or most uniform) service.
But they're the only agency that actually rents cars I have any desire to drive.
I got a brand new full-size Volvo S90 sedan for what all the other agencies charge for a janky Corolla or something. And this wasn't a lucky upgrade scenario, they just had better cars at lower prices when booking.
Rented a Jaguar F-Type from Sixt during a trip to Miami. Service was great, car was awesome, and I paid around the same I would have for a 4cylinder Mustang from somewhere else.
