I use multiple web hosting solutions and I'm pretty satisfied, although I would change a lot of things, first starting with adding some SEO options to the mix.
I guess you can tell that I'm pretty satisfied with my host, but I think this is because my sites are not that demanding and they don't require special care and attention at the moment.
It's pretty late to jump here, but let me know what kind of changes you want. I mean, your demands regarding to customer support or anything. It is more important to fill those loop holes where customers think somethings are lacking.
