Rylai's does stack with ability slows - at least multiplicatively, i.e. ~81% slow on E-max. In addition, it gives some health, which noone would complain about, and a big bunch of AP.

If you need RoA, then go for it. I personally tend to make my CC as deadly as possible - I wouldn't go for Rylai's if the ice blast wasn't a single target spell.
