Ocaml vs. Haskell

Ocaml: small, compiles very fast, runs very fast, very convenient imperative and OO features for times when things just need to get done

Haskell (GHC): conceptually and visually pretty code, cutting-edge, very slow and memory-consuming compiler, occasionally fast but usually slow runtime (but faster than java), purity and laziness sometimes problematic, records suck

which does /prog/ prefer?

Haskell. I'm an xmonad user and I'm writing a system in Haskell for the management of my company's ebay stuff. Mmm enterprisey.
