I finally saved up enough money to get MP-10, and it arrived yesterday. First of all, this figure is pretty amazing - less QC problem comparing to MP-09, and very accurate to cartoon Prime. For the past several of months I read and watched many reviews on this figure and many of the collectors claimed this figure will replace their MP-01/MP-04. REALLY! to me MP-01 and MP-10 are completely different species, they are awesomeness in their own way, just to name a few: Things I like about MP-01/MP-04: 1. Die cast very like classics Optimus Prime. 2. Wheel suspension 3. Hydraulic at all the joins 4. Lower legs are not too bulky etc... Things I like about MP-10: 1. G1 cartoon accurate. 2. In scale with MP-09 3. Very highly articulated. 4. Able to store the gun on the back etc... It's a WOW every time I looked at MP-10, and adore the MP-04. It's so hard to say which one is better. Just like comparing Ferrari Testarossa vs. Ferrari Enzo or Lamborghini Countach vs. Lamborghini Dialo. To me, MP-10 is an extension of MP-01...meaning it is complementing to MP-01 and vice versa. Which one is your favorite? is MP-10 replaced your MP-01? and Why? want to know your opinion on this.
