OM-D vs GH3 for still

I know this site is primarily a Panasonic m43 gathering place  and I realize if I was  interested in video Panasonic is seemingly the clear choice though for me I am a landscape photographer and was looking to put together a small light weight system when I don’t want to lug around my much larger DSLR system or my Medium format equipment,

The general consensus is the OM-d for stills is sharper the GH3 due to Olympus use of a lighter AA  filter.

though the gh3 has better ergonomics. 

Any advice?

i only shoot primes also.
