So which is better? "GH3" or OM-D?

Louis I confess I'm surprised you don't already have 149 replies to this baying for blood from every fanboy of either brand... 

I suspect it depends on what you use the camera for and what your shooting style is. I find the ergonomics and handling of the GH3 far better than the E-M5, even with the grip. The sheer number of physical controls is also a plus as is video. I suspect that the AA filter on the GH3 is marginally thinner as the RAW files seem ever so slightly sharper but also ever so slightly more noisy at base iso.

The E-M5 wins on stabilisation, small size and looks.

Both cameras take excellent stills. For me I prefer the GH3, but that's because I value controls over stabilisation etc.
