You are still white balanced incorrectly for both cameras.
The Sony is better because (aside from the fact that Sony makes better camera's than Panasonic), the SONY is a 1/2" THREE chip camera, and the Panasonic is a 1/3" SINGLE chip camera.
A single chip camera requires debayering, that substantially reduces the true/effective resolution (relative to the seonsor native resolution) (which is why you actually want a chip that is much higher resolution than what you are "ending up with" for single chip cameras).
As for AE workingspace: Set AE to:
32 bit
sRGB
Linear
Compensate for Scene Referred
WORKING SPACE:
If you are shooting with a dSLR like the Canon, set it to sRGB, and make sure that sRGB is the colorspace that the footage is INTERPRETED as in AE.
If your footage is from an HD camcorder, then it will most likely be Rec709, and should be interpreted as Rec709 - but your AE
working space should still be sRGB linear.
REASON: Rec709 and sRGB both use the same primaries, however, the gamma curve of Rec709 does not linearize well as a working space in After Effects (appears to a be a bug).
