Both the CRJ and the Citation Encore the heated leading edge is considered "anti-ice"... I've never seen a lot of water run back on either aircraft unless there was ice buildup before we turned them on and we melted it off. Usually it looks like it hits and evaporates.

When talking about aerodynamics, some manufacturers build aircraft that have "aerodynamic" deice/anti-ice. For example, the CRJ doesn't require the wing heat to be on above 230 KIAS. Also the CRJ doesn't have tail deice or anti-ice.
