Where it does out do any other lens I own is as a tele walk around lens, and it is the first lens I pack when I am about to travel abroad.
The only other lens I would consider in this focal range would be one of the three available 70-200L lenses - with the advantage of being constant F4 aperture.
If $$$ are playing a role in your decision - keep an eye on both Ebay and Gumtree, although the latter is less safe unless you are personally inspecting and picking up the lens before you pay.
