I sometimes put up a list of all E/FE lenses with various stats. You can find the latest list, from around a month ago, here .
That list is ordered in terms of focal length, Just for something different, below is a list of FE lenses, ordered by their ratings (out of 5) on B+H and Amazon. I've updated a lot of the ratings recently.
The list is ordered in terms of a bayesian average, which is how a lot of websites rank things (e.g. IMDB top 250 films and boardgamegeek ). It works such that a lens with a single rating of 5 does not shoot to the top. Instead, it finds the balance between having a high rating and a good number of ratings. If you want to argue the merits of the bayesian average then please do that someplace else.

This is a ranking of the best rated lenses on two websites. It is NOT necessarily a list of the ranking of the best lenses. You can probably come up with lots of reasons why the B+H and Amazon ratings are somehow flawed - I can too (e.g. low rating because of Amazon delivery service etc etc etc). Don't get too hung up that your BFF lens is ranked only at number 11 or whatever rather than number 1 where it really deserved to be. Its just a list for general interest. The ranking for lenses with very few ratings (e.g. 100mm STF and the Loxia 85mm) will obviously change as more ratings come in.
That said, the rankings unsurprisingly do line up pretty well with what 'general opinion' seems to be. My rough impression of what people are basing their rating on is that it is a combination of absolute quality and value for money, probably around 60/40 or 70/30 I reckon. In a few cases something else is a significant factor - the obvious one being the GM 85mm f/1.4, which got a lot of low ratings because of noisy AF.
Almost all of the lenses here are really very good - just because a lens is in the second half of the list doesn't mean its bad and even the bottom few lenses have their supporters. The key is to do your research and understand what you are buying before it arrives.
