I just got these today. I know it's not much but it sits nicely on my working area. The details on Megatron is so good it'll make you wonder why they have not done this color scheme with the leader class nor voyager class. I guess we have to wait for a statue to get the look we want. Anyway, there's nothing fancy over these two figures, it comes with faction symbols as base. Optimus' details are great except for the head. The figures articulation are on the head, both arms, legs thats it. By the way, Prime is heavier than Megatron since Prime's legs are mostly die-cast while Megatron has only die-cast on both feet.
If you find 'em get 'em.
