Why is the EM5 so much more popular than the GH3?

As difficult as it was, I went ahead and gave the rest of your post a read, and nothing you wrote backs up your assertion that "the GH3 ... is a better stills camera than the EM5."

It may be a better stills camera for you. Perhaps that's what you meant, and if so, I can't argue with you there, but to say it's objectively a better stills camera, well, that's just silly.
