Samsung 20MP vs Sony 16MP

I used both. The most significant difference between the sensors is the Sony's higher DR. The Samsung has a bit more resolution at low ISO, and the Sony is about 1/2 stop better at ISO 3200 & up. If you shoot raw under normal lighting conditions and use the same processing the results are more or less identical. The main differences between Samsung and Sony cameras are in features, ergonomics and lenses, not image quality.
