Thanks for the suggestions. Actually I'm thinking the extra 70-100 can be quite valuable. You can always do some cropping on a 300 mm shot. Maybe I haven't experienced the awesomeness of a 400 mm lens though.

The Sigma 100-300mm f4 has a very mixed reputation. At times it gets to be touted as one of the sharpest lenses one can buy, at other times it shows to perform poorly. What is the cause of the inconsistency of reports I do not know.

On the Canon 70-300mm L: It depends on what you want to use it for, whether it is a good idea. At "infinity" it performs nicely. At close focus stuff, it does not, at minimum focus distance the focal length shrinks to such an amount that the lens gives the same FOV as the canon 70-200mm lenses. Maybe that is a deciding factor?
