I highly agree with Artashes, as such there is no definitive or universal set of top 10 "services" as the service essentially is the same across the industry give or take a few. Personally I see top 10 websites being little more than the marketing playground for larger hosts through affiliate schemes and without which they would not exist.
Take into consideration a "product" such as a camera, essentially it has 1/2 main purposes, to capture and or record images... so to formulate a top 10 of cameras id set a price bracket and then compare the "Stats" and "add ons" for each camera then subsequently pick the best option for me from those results. Easy, however for hosting we do not provide a "product", only a "Service" and subsequently the stats or performance cannot be gauged when we purchase, only assessed over time as such we cannot formulate our top 10 on the stats that as a consumer we don't have.
So essentially the only way to decide a top 10, is an in depth view of the provider and the client, by which you store a numerical value of rating of the company in areas such as uptime, server load, customer support etc over the period of no less than 6 months. You then allow the user to select essentially what they are looking for based on such statistics and show the closest matches in order highest to lowest.
Rather than the current "whoever pays the most is n1", however such a system as above could still use affiliate links and other add based methods of profit as well as informing the user "support us by clicking here" and as such essentially it acts as a search engine to refine results, an enhancement would then be to tie such a system to forums such as HD ensuring reviews can be publicly scrutinised though essentially the rating is not derived from such a reviews, perhaps only a public opinion?
Personally the above would suffice to me as a personal top 10 research method, and I would require a sharp push to include a price comparison as its not essentially needed however such a site would require a large amount of warning as well as robotex and similar results summarised.
