Go to the compare sensors page on DXO mark, pick a recent FF camera and an m43 camera, and take a look at dynamic range - print. Take the manufacture ISO values instead of those marked on the graph, and compare the dynamic range in EV. You may also look at tonal and color sensitivity.

OK, so I looked at the GH1 vs. the 5D and they are almost the same from ISO 100 -ISO 1600.

How could this be? Sensor technology shouldn't matter too much if what you say is true.
