Best philosophy book publishers in English? (UPDATED)

MOVING TO FRONT FROM YESTERDAY

We haven't done this in about five years, so here goes:  rank these publishers by the quality of their catalogue of philosophy books in English.  Some, of course, publish more than others, so think of this in terms of something like per capita quality as it were:  if a book appears from this publisher, is it likely to be a good, worthwihle book?

UPDATE:  In view of the pattern of strategic voting for MIT Press it may be necessary to drop it from the results.  Cut it out. 

ANOTHER UPDATE:  I've closed the poll, the results are garbage.  The strategic voting for MIT Press has now been outdone by strategic voting for University of Chicago Press.  Before the mischief set in, Oxford, Cambridge, Harvard, Princeton, and Routledge, more or less in that order, were the top five.   A notable result, even despite the strategic voting at the high end, was that Palgrave MacMillan did quite well, "top ten-ish," as it were.  That's consistent with what does seem to be a strong set of authors/books in the last couple of years.   Since these polls have become so important that some folks now feel the need to fuck them up I guess the only alternative will be private polls, with invited respondents.  This will take more work, so won't happen soon, but at least the results will be better.
