To be frank, the "best" depends on too many factors that it's almost meaningless to make such a claim, and in some cases, it may be the *only* choice which automatically makes it the best in that category. But being the only choice doesn't necessarily translate into a good product.
Also, choosing the products because someone claims it is the 'best' is more likely to be the wrong choice than choosing one that meets your needs/wants satisfactorily and within the budget. Thus my reluctance to name a best server, even if we could come to define such things.
