Pratchett, unquestionably, never mind what "people who matter" think. There is so much packed into his books that I get more out of them each time I read them. There is no other living author who does that and does it after ten or more re-reads, although I will say that our fine host's client Dave Freer is fast-approaching that level. Sarah Hoyt is another one who's heading for that level, fast - and both of them are grossly underappreciated by the "people who matter".
