The 300mm f/4L IS USM does need to have IS switched off when used on a tripod for best results. The EF 24-105mm f/4L IS USM should be able to used on a tripod with IS activated without diminishing image quality. |

Take a look at this article (complete with photo comparisons):
Why IS and VR Matter

I've been using my only VR lens today and as it was still mounted when I came home I shot a quick test. Both images are reduced in size here and are clickable and lead to the bigger versions at pbase.
Scene:
Crops:
Lens is the Nikkor 70-200 VR @ 180mm (270mm crop on DX body) @ f/2.8, these are 100% crops (camera sharpening off). Focus distance about 160cm.
On the left 1/6s with VR on. In the middle is 1/6s with VR off. On the right is 1/8s with VR on.
All handheld. When you lock focus and give the lens and yourself some time to get stable, you can get something like the crop on the right. I can see the VR at work in the viewfinder and hear the buzz inside the lens. Normally you'd like to use something like 1/250s here, but with VR on you can get acceptable results 5 stops slower..... (1/250-1/125-1/60-1/30-1/15-1/8).
I wish I had this on my 30 prime or 12-24. It would help a lot with shooting static objects (like paintings or statues) indoors where a tripod and flash are not allowed. Either more succes because of higher shutterspeeds or the option to use slower ISO.
Edit:
The middle one is the best handheld, I have some far worse.
