Is Orbitz relevant these days?

I use Orbitz to compare car rental rates when I'm flying into a particular city on a specific date. Then, once I figure out who has, what appears to be the least expensive rate, I go directly to that website (but visit a second or third specific car rental website, as well). I don't use Orbitz to make a rental car reservation.

Back-story: I used to use Hertz exclusively, but no longer. Hertz's rates can be way over the top in certain cities. And, when I think of all the car rental companies that I've used, Hertz seems to be the most efficient in getting you out (but that's likely because I was in the President's Circle and now, Gold, which is fine). I use Alamo a lot, but their algorithm at the self-service kiosk seems 1990's antiquated - it is s-l-o-w and clunky. I like Budget, but it's never quick to get off their lot. Same with Avis. I tried the "after-market" :-) rental car companies (Sixt, Fox), but good grief - the desk service has been a nightmare!
