Dig up all the lens reviews and tests that you can find, because even the L-series do vary from model to model. One may be stunningly sharp and the other L only very good. I'm not in the market for this range, so I don't have a clear opinion, other than Ls are worth saving for. You never know, but some of the non-Canon lenses are particularly sharp, like the Ziess wide angle, so don't limit your search to Canon. Limit it to very high quality glass.
