I really love the mkii of the 24-70 and on a ff it's a great combo.
Yup, it a killer lens, but heavy and expensive. Don't get me wrong, it's a superb setup if that's the way you want to roll. For me the extra 35mm of zoom, saving $600 and having IS makes the 24-105 ideal (for me at least).
Many don't worry about IS saying it's wide angle and you don't need it, but I use it all the time. I can handhold landscape images at higher F stops if say I am hiking and didn't lug along a tripod. All depends on your style and intended use .
I do know the MKII of the 24-70 and 70-200 are reputed to be insanely sharp. I just didn't (don't) feel like the 24-105 is any slouch there. I got upgrade-itis a while back and considered getting the MKII lenses. After looking at my images and weighing out the expense and physical weight I opted to keep what I have. Well, I did get one MKII lens, but it's the 500mm one
