The most common things I've heard from people ( friends or strangers in line with us ) on the last three trips to Carsland was that they seemed to enjoy the value of Mater's Junkyard Jamboree over Luigi's Flying Tires. I am by no means saying it's a better ride or that I think that way, just passing along the consistent observation.
Personally I love Luigi's because it's a re-visioned version of an old Disneyland ride and I finally get to ride the thing. I respect that the technology that went into it seems to be more than that of Maters.
....and yet I really have to focus on the word "value" and point out that you'll typically have a shorter line for Mater's for a ride that takes about the same time and might come off as more fun because it really whips you around. I love Luigi's but have to notice that not everyone has a great time on it. Some people have a frustrating time because they're not clear on how to fly the tire, or maybe they get boxed in by a few other customers and their whole ride is being stuck in a corner.
They're both good. If you went to DCA and didn't go on them I think it would be a regrettable shame.
It's super fun and so cute! I like while waiting in line when you can see the ride, looking at kids either having the time of their lives or holding on for dear life and screaming. (Just interesting to see some kids love it, some kids are traumatized for some reason). Anyhow, my friend pointed out to me last time we went that all the cars have different shaped mouths which I never noticed before. I like the ride a lot. It's themed really well and I like listening to Mater's singing.

when i went in september, luigi's had a 30 min wait, and mater's had a 5 (!) so we went on it. it's really actually fun... like and old school fair's 'salt and pepper shaker' or 'whip' carnival ride. we never actually made it in to luigi's, the wait was always way too long, but we hit mater's a couple of times.
