low detail but even high had the legs correctly one behind and one in front of the frame, don't remember other models getting it correctly at this low level of effort

There's no legs on low and medium.

High gets legs correctly, but screws up the layering on the chain.

x-high is very good but there are minor laying error with the front chainring.

I don't know, for me they lost the fun and whimsy aspect too, a long time ago. They have converged on more-or-less the same design (facing right, pastel color palette, etc.). Some of the lower-effort ones are a bit goofy at least, but now even that is being polished away.
