Ok Mine imator is a great piece of work but comparing it to blender is like saying 720p(mine imator) is like 1080p(blender).. They are nothing alike. Granted cinema 4d or maya are more like 4k in the analogy, blender is an amazing VERSATILE program capable of modeling, animating, compositing, built in game engine and soooo much more. You could actually recreate slamacow style animations with it instead of dreaming of it.
With that said mine imator is a great program for beginners or those who don't have the time to learn or animate with a professional grade animating program.
