Leader Megatron
-Reasonably screen accurate in bot mode.
-Mech-alive gimmick on this one is actually pretty cool.
-Crappy non-articulated right arm
-Left arm too small (I can tolerate this though)
-My biggest complaint: tank mode is not screen accurate, but at least it does look like a tank.
Voyager Megatron
-Reasonably screen accurate in bot mode. But the colour is off and now comes with back kibble.
-Much more articulated and poseable.
-Screen accurate arms.
-Tank mode is a lot more screen accurate in terms of shape, if you ignore the colour.
There's also a difference if you purchase Megatron purely for the toy itself, or if you purchase it to display with other ROTF toys. If you're purchasing for the later, then I would choose Leader Class over Voyager. Leader Class has good size and is imposing, looks nice standing next to Leader Class Optimus Prime.
Since you have already bought the Leader Class one, I would only get the Voyager one if you already have a Voyager Optimus Prime and Voyager Fallen. These 3 display very nicely together.
