I've decided to just keep on truckin' with my LG version, which I have loved for a long time now. He's tiny and simple, but he just works for me. The mold references his G1 model close enough for him to stand among my modern '84 bots, but he's ever so slightly updated, which is nice.
There are parts of the SS86 version (like his legs and feet) that just look too doofy for me to take the plunge on. He's got a huge noggin, seams that run the length of this legs, weird little hinges all over the place, and tiny, boxy feet that just don't look good, IMO. I do appreciate the amount of creativity and engineering that went into his transformation, but the end result is really uneven. Basically, I don't mind how he looks from the waist up. But I'm not swapping out my LG version to get another version that I only like half of, just because it's new.
