The swivel wrists are great, but plenty of new sculpt o-ring figures had that as well, it's not unique to the 25th style of figures. The main reasons I dislike the 25th stuff are their fragility, their limited poseability, their mostly skinny and poorly proportioned bodies, and their larger scale. Plus I hate how Hasbro arrogantly expects that someone who already has all these characters as ARAH figures will buy them all again just because they have been "re-imagined".
As a few others have said, the o-ring IS GI Joe.
