i'm at the point where i have to make a decision. I just sold my d7000 /18-200mm to buy a CSC.

i like the OMD em1,

the only thing bothering me is dynamic range.. and especially NOISE..

Noise level depends on the size of the pixels (not simply the size of the sensor but how many pixels are packed into that area), the development generation of the sensor (newer sensors are usually better), and on the contrast of the lens (a more contrasty lens will give less noise).

Dynamic range is mainly a side effect of noise, assuming you avoid clipping the highlights.

So, if you compare two sensors both with 16 Megapixels, the bigger one will have less noise. But if the bigger one also has more pixels, there may not be much in it. And if you use a brilliant prime lens on one and a low contrast zoom on the other, that could cancel any improvement.

For best results use a first class prime lens on full frame. For example, the Sony A7 with a Zeiss prime lens.
