One little addition:

Unlike two surface canard, a three surface aircraft achieves both: high Clmax and minimum trim drag. Canard only achieves minimum trim drag and low Clmax where conventional achieves normal trim drag and high Clmax. Three surface is a kind of best of both worlds. The forward wing can be also tuned so that it makes the plane stall proof. There is one downside though: the protruding wing in the forward fuselage spoils the airflow over the fuselage potentially causing an otherwise laminar flow to become preliminarily turbulent. However, planes this is compared with don't maintain extensive laminar flow over the fuselage anyway, the fuselage shape has to be like in best sailplanes for the forward section with no joints, protrusions, pitot tube, access doors etc. to achieve the laminar flow potential anyway.
