I just got my MP Prime (ok, 20th to be exact) and this is THE coolest TF ever! At least until I get my hands on MP Megs! Anyway, Im hoping to get Movie Prime for my B-day in October and figured this would be a good "VS." topic to discuss: 20th/MP Prime to me is the greatest TF ever because it is SOOO accurate to the G1 toon and everything Ive waited for in a Prime since then! The conversion is cleverly engineered; it was amazing to see that nothing in the Alt mode or Bot mode was sacrificed... I love how the snap on hands and box torso were eliminated! The front tire/rib cage coversion/design that includes movie accurate spark is brilliant! Also the pistons on the joints add to the realism and was an extra "goodie" that made this huge guy feel like a REAL collectors item not just a big ass toy (i.e. Ultra Class Starscream). This Prime is essential!!! As for the Movie Prime, I dont have so I'll just say why Im GONNA get him. 1st off, its a super cool design for Prime as a long nose big rig in both modes... Accuracy to the movie seems great. Plus, he's big!!!... Dont know if he'll be as impressive as MP but I know it will be on my helf eventually! Can anyone comment on size comparison to the MP version and to Alternators?
