Let me clarify a bit more, the meaning of best for me in this case is the lens that is a compromise good value, performance, and price while having excellent IQ. Image Stabilizing is a plus, since I am doing free handle most of the time.
I have thought about the 16-40 f/4. But, I heard that the 24-70 is one of the best lens to get after 24-105 f/4 and it is a great all around lens when shooting street photography.
Given the 1/focal length rule of thumb (for a shutter speed that prevents your movement from affecting images) the question to ask yourself is: will my subjects generally require a higher shutter speed? My time is mostly spent hunting a small person these days, so even 1/70s isn't usually enough. Thus I tend to be at faster speeds than required for the focal length, thus IS isn't a big deal for me for this lens.
If this was my main lens for handheld architecture and landscape work, IS would be really useful.
So, if you don't need IS, and can afford it, the 24-70II is superb optically and has very fast AF. If you need stabilisation and f/2.8 the Tamron is very good. Canon's f/4 IS is good otherwise, though I believe it's a little less sharp at 50mm.
