I've got a Carter and a Holley on my two cars, and have had no problems with either. They're both mounted solidly to metal and are L-O-U-D. An EP car I just did some work on has some rubber grommets and that thing is almost as silent as the stock pump, so I recommend making sure you mount it with some grommets or something else to dampen it.
Most important from being under several different cars is to mount the pump near the bottom of the tank so you don't run into problems with it sucking air.
