Can only recommend RS 4000.
(Yes, there's a vServer in the domain, but it is the root server)
Not entirely true, they are V-Servers with the characteristics of a root server and that is a world of subdivision. These servers are on a very large scale and share the performance with others. You own a root server alone and do not share anything with anyone. Therefore, pure root servers are also far more expensive.
