I was hosting with GoDaddy but now only use them for domain registration. I'd say their managed service is for people who have a simple website to host. If you're looking for something specific from your environment, then any kind of shared hosting wouldn't be appropriate. I don't have any experience about Rackspace. Having said that, I now host on webfaction which is still a shared host but they're developer friendly and usually accommodate requests(libraries or apps on server) if it's reasonable enough. As a customer, I recommend them.
