I looked at both of these lenses and purchased the 24-105
The 24-105/4.0 is about 23 oz and the 24-70/2.8 is about 33 oz. The 24-105 has IS but I don't believe the 24-70 does. I purchased the 24-105 for about $950. I think the 24-70 is about $1200. Both had good reviews and both have been around for a while. The weight and focal length were more important to me than the speed so I went with the 24-105. The IS works very well. I use this lens as my carry around lens and have been very happy with it. It takes great photos.
Just tonight I told the wife that the 24-70 was next on my list. Then I remembered that soccer season starts pretty soon and with my kids moving up to the larger fields I started thinking about the 100-400.......
Anyway, between those two you mentioned, I would go with the 24-70. For me, nothing compares with a fast lens.
Which would you choose and why: The Canon EF 24-105 mm F/4L or the Canon EF 24-70 F/2.8L?
Have you made your decision?

I have the 100-400 and very rarely use it after buying the 70-200 f2.8IS.
I would see if you could borrow one first to make sure, as the 70-200 seems to be more useful for most people
