Hi Issac,
I agree with your conclusion.

The main effect of the LE flap is to increase critical AoA and CLmax by delaying flow separation. In addition, some additional lift is created at lower angles due to the increased camber.

A slat, however, only re-energise the boundary layer and therefore does not help at low AoA.
