There is a way to make the 24-105L as good as the 24-70II for your landscape pictures: shoot in portrait and stitch. You'll be using a longer focal length so no need to worry about the rather 'added afterthought' results of the 24mm end.
If I was looking to use the lens for shallow dof portrait style images instead of primes I would go for the 24-70II if affordable. Test charts don't give the full picture.
No way. The sharpness, distortion and CA get worse and worse as you move to the corners on the 24-105. The 24-70f2.8ii is a dream all the way to the corners even wide open. You can stitch all the soft (relatively) images together you want to and it still makes a relatively soft panorama. The 24-105 was my go to landscape lens for 5 years. I have made thousands of images and hundreds of panoramas with it and used all focal lengths from 24-105 to do it. Panos with the 24-70ii are simply stunning.
Depends on the focal length and overlap that you are using. I avoid 24 mil on the 24-105L, and my panos are generally shot between 35 and 60 mil, most of the time f8, always portrait orientation. With a generous overlap I cannot, in the (large) print see a practical difference between the 24-105L and lenses such as the 35L and 50/1.4.
For single frame shots the 24-105L would not be my lens of choice for critical landscape work.
