I'm a huge fan of water-soluble flux, and prefer it when doing SMT 
stuff. Of course, it's a little less reactive than rosin, so you need to 
really inspect your joints after soldering.

My only complaint, and it's a small one, is that you really do have to 
clean it off. The flux is naturally hygroscopic and will, over time, 
increase its conductivity to the point of affecting the surrounding 
circuit. This is only a problem if you use the water-soluble flux on 
everything including prototype boards you might normally leave 
uncleaned. Fortunately, cleaning the flux off the board is such a 
trivial matter there's no real excuse for leaving the flux on.
