Higher HP tunes usually result in more gains in the MPG department. That being said, I'd say the Mini Maxx will get you more, because it has larger tunes.
Another thing to consider is that the XRT does not tune the transmission, which could lead to transmission issues later on down the road if you beat on the truck, or tow a good amount.
Originally when H&S was getting their tuners out, they were supposed to be a cleaner tune, and I think a couple of people said they don't really blow a lot of smoke like some others do.
