What aerodynamic characteristics arise from trailing edge sweep angle? I drew 3 wing planforms, each with the same leading edge sweep. But they have different trailing edge sweep.



Let's just assume for the moment that all those wings have the same surface area, so that they all have the same total lift. What would be the different aerodynamic characteristics due to the trailing edge sweep angle?

Note: let's leave out considerations of control surfaces. Obviously the first wing would have the easiest implementation of control surfaces, but I want to focus on what the static wings do.

I looked into this and that related question. IMHO they're not quite the same thing as what I'm asking here.
One aerodynamic behavior appears at high angle of attack : dihedral or anhedral wake, which affects (in some weird mixture) both roll and yaw stability. Forward swept trailing edge is much more stable than backward swept trailing edge. 

Some jet fighters (let's say F-22) and most aerobatic airplanes (let's say SU-31) adopted forward swept trailing edges in order to increase stability at high AoA.
