I had the exact opposite reaction to GDO Swerve. I think he's a great reuse of the Generations Kup mold. He's replaced the Chevy Aveo Swerve I used to have on my classics shelf. The fact that the GDO version is a truck, like the G1 toy, helps a lot, and the color scheme is very striking with the bright red and white and black highlights. It's too bad he didn't get a newly tooled weapon to distinguish him even more from Kup, but the head sculpt is excellent.
Wheelie is also an amazing surprise. The head sculpt really sells it, along with the new slingshot accessory. He's in storage now, though, as his scale is just too big. Scout size might have worked, but his legends size Universe figure fits in my classics display so much better.
I like Springer a LOT. I don't buy the third party "homages", so I don't have a Warbot Defender to use in my display. Of the Hasbro releases of "Classics" Springer, this is the best yet, IMO. The 2007 BotCon Springer was good, but bulky. The Universe repaint of Cybertron Evac was passable. But GDO Springer finally has a face sculpt that does the character justice. The new sword for him is also a great touch and a detail Hasbro could have just neglected. I think it shows some actual thought was put into these repaints and retools.
GDO Cliffjumper is the least exciting. I already had two versions of the mold with First Edition Cliffjumper and then the SDCC "Rust in Peace" version. Still, it's a very good mold, and the darker red for the GDO version looks sharp. The G1 head sculpt is also quite nice. After looking at him along side the other '84 Autobots in my Classics display, I decided he looked like he belonged there, despite being a very different car than his G1 self. At least he isn't just a straight up Bumblebee repaint, since he never really was in G1. My Classics Cliffjumper is now in my stoarge box of "extra" representations of characters. Although the mold was originally made for a Prime toy, with it's distinctive aesthetics, it's blocky enough without too much "robot detail" that it is a plausible Classics figure in my eyes, especially with details like his chest being composed of his windshielf and roof. It certainly fits that roll more than TF2010 Tomohawk as Springer, and you know already I love that Springer as his classics representation.
How do people feel about the other size classes? I could rave for a while on these, but I'll try to spread out the walls of text across a few posts
