I only have two of my own (both deluxes) so my views on the other sizes are based on: images, seeing them in store, reviews, and video. Deluxe-Barricade, hands down. He is probably my single favorite deluxe EVER. The detailing on his alt mode is just downright amazing. His bot mode isn't perfect (hips don't quite lock into place), but it is certainly intimidating and has some decent articulation. Only other complaint is his "long arm of the law" action feature tends to deploy itself and that can get a bit annoying. His transformation is simple enough, but still fun. Voyager-Starscream is an impressive figure. He is close to the movie model and again has an intimidating look to him. His jet mode has some problems (primarily due to parts being exposed and his undercarriage). However it is nicely designed alt and looks nice. His bot mode is solid, has good articulation (minus hips), and again looks close enough to his cgi model. His transformation looks fun and not too complex and his a nice automorph feature. Leader-Prime is a perfect example of a well made leader figure. I'm not a big fan of electronics and what not for figures (espescially transformers) but they don't really take away from him. His alt is well made, looks nice, and is a good representation of him. His bot mode is similarly impressive and stands out. His automorph is appreciated.
