The reason is that I do Scala at my day job, and thus I'm simply more experienced in that than Haskell.
While I've written a compiler in Haskell in the past, and prefer the language in many ways, I don't know how to do front end programming in Haskell, compile Haskell to efficient JS or debug performance problems. I also don't know if there's a good Haskell IDE these days. PureScript would have been risky for me, since I haven't done anything in it before.
