Scrapmetal really surprised me. I got him along with SS Shatter and SS Dropkick on the weekend and he was the one I was least looking forward to, yet ended up impressing me the most.
I know I'm not saying anything new here, but he feels solid, has a fun intuitive transformation and looks good in both modes. He technically is a partsformer, but that panel that goes on top of his vehicle mode isn't really necessary IMO. If you lost that panel or just chucked it in your parts bin, it wouldn't hurt the figure to not be there. Most importantly, Scrapmetal really feels like a Transformer as opposed to a shellformer, which has been all too common in Studio Series (yes I understand it is necessary for screen accuracy).
Definitely recommend picking him up even if you never intend on completing Devy, he is an excellent figure in his own right.
Looking to buy lucky draw Armada Prime and Diaclone Marlboor Wheeljack.
