I'd go to fox only because they were pretty dirt cheap. $25/day for our one day rental during spring break. A taxi would cost upwards of $50 so I can't complain too much. The cars, however, were disgusting. I had an experience with fox in LA. all they had were shitty PT cruisers.. so my expectations for the LV airport weren't too high. THe first day, we got a chevy economy car that was actually decent. On out last day, we had several cars to chose from. The first one my husband jumped in didn't start. He jumped in a couple others.. they were all disgustingly dirty. He settled on a kia. It had stains on the passenger seat and back seat. The odor of coffee was stroooong... It could've been worse, I guess. So although I can't rave about this place, I'd use them again since we only needed the car for a couple of hrs to get to my parent's house/car. If we were going to be using the car for a few days, that'd be a different story. Oh, you know that free shuttle that takes you from the Mccarren airport to the car rental center? You need to wait for another shuttle to take you to fox since fox isn't in the car rental center with budget/enterprise/etc.
