The zoom vs. prime debate will always come down to what your subjects are, and what else you may carry. For me, in variable situations where I'm not often targeting a single subject, a zoom is invaluable. For sure, I probably use the 100-400L at 400mm most of the time. But it isn't 100%, and I still take a significant number with that lens at shorter focal lengths too. This can be mitigated somewhat if you use two or more bodies.
