Canon 5D vs. Canon 40D and Canon 60D - A qualitative comparison

Canon 5D vs. Canon 60D
I made this comparison while on a trip and I would say this comparison is not entirely fair because the setting on the two cameras are not the same.  First, lenses were different. A Canon 50mm f/1.8 lens was mounted on the 5D and a Sigma 30mm f/1.4 was used on the 60D so that both cameras had the same field of view. Second, the 5D shot in RAW mode while the 60D shot in JPG mode. Also, ISO was set to the lowest possible value on each camera, the 5D set to 50 and the 60D set to 100. The width of both images were scaled down to 2400 pixels in GIMP for convenient web uploading. This image size still allows us to see the difference in image quality in the two setups.

Canon 5D + Canon 50mm f/1.8, aperture f/7.1, shutter 1/100s, ISO 50 
Canon 60D + Sigma 30mm f/1.4, aperture f/7.1, shutter 1/60s, ISO 100
Surprisingly, the 5D outperforms the 60D significantly, not to mention that the 60D sensor resolution is 6 megapixels more than the 5D's. The details on the image by the 5D are sharper. The tree leaves are still visible, while on the 60D they are mostly smeared. The 100% crop shows the difference clearly.

Update: 
The comparison above is not fair since the image taken with Canon 60D is in JPG format.
