The older I get the more appealing the size-weight thing becomes.
With the 70-200mm versions I have had I have never remember saying I liked it for its wonderful bokeh. I could always do a quick test of sample pics of the two if any one was really interested in seeing it.
IMO size is the reason to buy it.
