Panamax and Furman are (now, and for more than two years) the same company - Core Brands. Their is not much difference between the two per se, instead it comes down to model and purpose. Furman is oriented to those who desire voltage regulation, which is very different than conditioning and surge protection.
I have a Panamax MR4300 and it is great. Conditioning can be observed on an oscilloscope, the voltage shut down from over/under voltage does work, the voltage meter is very accurate, front panel lighting has various illumination levels, I could go on... The price is reasonable too.
