Both Leica M9 and Leica M-E Typ 220 have Full frame sized 18.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another difference between these two cameras is that Leica M9's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the M9 and M-E Typ 220 sensor size comparison.
Leica M9 and Leica M-E Typ 220 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
