We know all the issues with ones of the most disappointing figures of the year (Optimus mpm), but, here the main thing of the thread it's, it's really a "masterpiece" and superior to the original leader?, please take a seat and hear me out. Here's a little and mostly basic explanation of the Masterpiece line: It actually has better engeenering than the original leader class and it's worthy of the name 'materpiece'?. I'd say by various investigations with depth i made so far, in my most objective view of it, it isn't. First of all we should compare both designs, the accuracy they make, prices, budget limits, final product, quality wise, etc. DESIGN & ACCURACY Vehicle Both are trying to represent the first CGI model of the first trilogy from th live action movies. Both transform in the Peterbilt 379 truck, both have their flaws and hits in the way they are made to represent a toy form of it. However, there are greatly and noticeable differences between both in the alt-mode. Here's an image to explain better: We are going to ignore the poor tolerances in the mpm version to focus in the accuracy. As you noticed, the mpm does a POOR job in hiding all the robot bits or kibble in the alt-mode wich it's surprising considering the ROTF mold was made like 9 years before, and this makes me feel they didn't found a proper way of transformation scheme, because it still cues some of the transformation from the original leader. Both aren't perfect, as you see, both hood extend more than they should just as the cabs. The undersized gas tanks, tool boxes, fenders, smokestack and rear head of the cab in the mpm, are proofs that the original leader was well balanced, both modes are accurate in someway without compromissing the other, that's why the leader's vehicle it's amazing among most of the fans who bought it, those poor proportions in the vehicle are not even in the Battle Blades Voyager from 7 years ago, and consider this, it was made for kids, not for "hardcore collectors". The original leader has been aged so well, his design it's actually ahead of this new time if you think about it, we still compare it to a new "high quality" item from the hands of Takara Tomy and Hasbro. Robot Here we go, both are actually pretty decent representations of it, to compare both with cgi model, i made this mock-up): There are great differences in the aesthetic, however, i think the ROTF leader does more the "MP" name justice, heres's why: -The chest in the mpm is too wide and has a major gap im the chest between the collar, while in the MPM the gap it's small, and not weird looking at. -The fenders in the MPM ruin completely the profile and sihoulette, also does the backpack configuration, while in the leader those aspects are secure and well-done. -The flames in the forearms are not existant at all and are cropped by the transformation. -The forearms have more detail in the leader and the panels extend far from them as the cgi model, unlike the mpm. -The abs are completely bulkier than they should and are in a wrong shape, if you look at leader you can see a "square" form in the top. -The doors in the mpm are incomplete, and they're too wide and thick, also the leader's doors does something like a MP would do to mantain the accuracy, faux parts. -The windshields panels are totally blocking the head range and view, coming in the cheeks. -The crotch its' actually better detailed than the mpm and the golden accents are in the right position unlike the mpm. As you can see, the leader does a great torso and crotc, but the mpm wins by far in the legs compartement, but just that, they should have refined all the body shaoe, that's the prhase that describes all the waste potential in the mpm; "what it could have been...". PRICES AND BUDGET The leader's price originally was under 50$ US dollars, in comparison with the Masterpiece Movie version wich price is the double now (100$) Further more, the japanese version has changed some bits and paint apps to cost around 140$. There was cuts of features in both figures, possibly the "working vehicle" for the mpm haha, those feature could change them in a substancial way, at least the leader class. In the leader, the toolboxes im the lower legs were going to split, so are the tires on thighs, the hands wer articulable and retractable, the paint apps were major in comparison with the final release. Now with the mpm. Just a little feature was cut, and it was the air filters to slide in the transformation, we can see it here. QUALITY WISE, FEATURES, PAINT APPLICATIONS, ETC. It's actually unfair compare the new MPM version with the original leader, we should compare it with the recent MB-11 that was for a similar price. The paint apps are similar, unfortunely... -The MB-11 uses silver for most of the robot with some grey bits. -The mb-11 has golden apps in some parts. -The Hasbro's MPM uses dark grey while the TT uses lighter plastic. -There are golden accents in the TT mpm unlike the mb-11 and MpM hasbro (with 40$ price of difference). -The MPM prime has some brilliant or light finished in the diecast parts. -Both MPM uses silver pinstripes while the mb-11 doesn't. FEATURES In this aspect, i think the mpm it's in the par or even better. -The mb-11 has a TON of sound clips, and has some light gimmicks. -The mb-11 still has the mech-alaive gimmick -The mb-11 comes with hooks and swords, also the ion blaster it's integrated while the MPM doesn't. -The MPM has removable matrix, ehile diecast, the accuracy it's non existant. -The mpm comes with a swappable face gimmick. -The mpm comes with 33 points of arriculation. Final Conclusion: While both does have flaws and hits, it's sad that the issues in the MPM version have so much weight, but the leader also does an amazing job in a lot of thing, the masterpiece version even without the QC problems, there are a lot of design liberties that aren't made for the MP line, and some others that the leader does even better. The mpm has lost potential that could have been made it one of the best TF figures of all the time. Don't tabs at all, poor job at hiding kibble, weird proportions, poor paint apps im both versions, wrong colours too, inaccurate transformation srtill. The leader was one steps to be perfect, but they turn in a 180¤ degress and they failed completely. In my opinion, if you don't have any of these, you should buy the one you want the most, but it won't make it better or worse than the other, but just....think about all of this.
