really? I'd suggest not with the exception of the E-M5.....
The Panasonic G3 is excellent value for money and the 16mp in the G3/GX1 is a step up from the one used in the pens and the Pan GF series.
The Sony's have better sensors than the Oly's/Panny's but there isn't the range of lenses.
And the Nikon's will toast any other mirrorless camera if you want to track moving subjects. Image Quality is comparable with the 12mp m4/3 cameras from Olympus and Panny.
The Olympus cameras are very good but look at the alternatives.
