Those are KOs by CHMS (guys that did the Henkei Seeker KOs). I think "blue limited combat" is G2 Breakdown but it might also be the Punch/CounterPunch KO since it's blue as well.
"White Combat" is G1 Breakdown and "Yellow Scud" is just Sunstreaker.
As for the quality of the KOs, they look the part but joints are loose all over with mold flash throughout. Plastic seems more brittle than Hasbro's. Rivets and screws are susceptible to rusting.
