Don't forget brand new Tamron 150-600 VC USD, which sells around 1200$ or so.
Image quality is quite similar to Canon 100-400mm while both at 400mm focal lenght. But you get extra 200mm reach for pretty low price and 500-600mm IQ is very usable, espacially when stopped down to f/8.
When it comes to IQ, prime lenses are ofcourse the best.
