Main reason I got "Sidearm Sideswipe" is that there is a likely chance this could be the last version (yes, i know this is Hasbro we a talking about here ) of Sideswipe that has a roof in Vehicle Mode ...
( same sort of reasoning why, i got "Premium Jazz" from the 07 movie line as, there was a very good chance he was not going to be in the Second Movie and i thought it was the best D. Class version he was going to get )

Anyway i got the Takara-Tomy Version "I considered it to be the best one, compared to the Hasbro version " and from my stand point the Takara-Tomy version is indeed the best one to get.



In case anyone asks yes , the feet are backwards in the Robot Mode pic....
The reason is that have noticed in this position, I can retract the "Front Toes (what becomes, the front toes after rotation of the feet) then make the rear toes higher so the wheels on both feet can spin .
