The first thing that caught our eye about Complete Internet Hosting was a great answer to my biggest complaint about hosting providers. Most hosting providers will suck you in with a relatively aggressive starting price, but when it comes time to renew, the renewal price can be two or three times the original price. I've even found one company that renews at more than six times the original price.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
WordPress being as big as it is, chances are, you are probably using it for whatever online project you are running or plan to launch. If that is the case, Bluehost is one of the best web hosting providers for you. However, you do not have to limit yourself in any way, shape or form. You can use whatever other CMS and still be able to rule the online world with a fantastic web hosting service for a personal website like Bluehost is. Do what feels right for you and your website and Bluehost will take care of all the rest.
In housing terms, VPS hosting is like renting your own apartment in a larger building. You're much more isolated than in the roommate situation mentioned above; it's still possible that a neighboring apartment could causes annoyance for you, but far less likely. In web hosting terms, Site A's traffic surge won't have nearly as much impact on Site B or Site C. As you'd expect, VPS hosting costs more than shared hosting. You'll pay roughly $20 to $60 per month.
