Without taking sides, I would say look at some books on each. Kinda like comparing plutonium and uranium, or a cello to a guitar. Maybe these comparisons are silly. While youre at it look at scala and O'Caml. You can look at the Yesod book, Real World Haskell and "Learn You a" online, i.e. read the complete, updated texts. Thompson's orange "Craft of FP" is a good read also, with methodical (and relatively slow-paced) coverage of all the basics. GHC is piling on language features and libs at a breathless pace, from deferred type checks, limited forms of dependent types, concurrency (async loops, STM, updated thread manager), IO abstractions (conduits), web apps (Yesod) http://hackage.haskell.org/trac/ghc/wiki/Status/May12 http://hackage.haskell.org/trac/ghc/wiki/Status/May12 Clojure is an incredibly well documented (in books) language. I'm looking at the excellent O'reilly and Pragmatic books, and the 2 Manning books ("Joy of" is terrific), all of which came out in the last 4 months and target 1.3. And i will wager that Marick's book will be top notch as well. Unfortunately, these don't have texts online.
