Twitch is the BEST out of the two (Sparks and Strech)
He may not have many articulation points, but he's just a really nice figure, he's very detailed, and he's just... awesome. He has golden-type wings, that are very clear. He has cool combat gloves and boots. You can make him punch, kick, and fly. I found mine at Meijers for $6.85. He is a MUST-PICK-UP.
