1 and 4 are slightly better IMO to.

Hodnik; here is a lesson I learned when I started buying L lenses. It is the Canon cost rule of thirds (3x), when you go from the normal non L lenses the new L version cost 3x as much. However, the improvement you get from going up to the more expensive version isn't 3x as much. It is fractional. You pay allot of extra money to get just a small amount of improvement.
