I really haven't found much difference between the rental companies. The fact is that all of the companies trucks get beat up pretty good and moving is a stressful time for everyone, so if there is a problem, it tends to get magnified. UHaul is the biggest company, so their problems tend to get magnified even more, but I haven't seen anything that says either of them are all that much better or worse than the others. I've most often used UHaul because they have lots more locations, so they can be more convient, and often are cheaper (although you can usually get the companies to price match), but I've also used Budget and Penske, and all have different +/-s but they really aren't all that different.
