In building a social commerce product on top of Magento, we were looking for a Magento Host that knew what it was doing and would let us focus on our value additions.
After a lot of research, we found Nexcess and I think they under promise and over deliver. I have not in the past 1 year of research seen a more optimized instance of Magento or a host that provides the kind of features they do for the $$ they charge.
Highly recommended! We started out with a trial of a month and now we are religious converts :)
