Om-D vs GH3 for stills image quality, which is better?

I agree, that personal experience with both camera is the best way to evaluate them. I upgraded GF1 to G5 and there are several small annoying things on G5 that nobody mentioned on forum. I decided to keep GF1 because it is better camera in some situations. The major disadvantage is that using 12-35/f2.8 or 45-200/f4-5.6 on GF1 is not comfortable, but when the weight of lens is not problem, ergonomy of GF1 is better (buttons are better accessible and much easier to recognize by thumb), it's more fun to use this camera and people don't expect good photos and don't care about you because it doesn't look like a DSLR.
