Except the 24-105 is regarded as a very very average L and isn't particularly sharp.
Indeed. There are tons of revealing tests, particularly the ones that compare it to a new 24-70/4, or even 24-70 2.8 II that I own. New lenses are head & shoulders above the 24-105 sharpness-wise.
The real bonus of sharp lens is the fact that in FullHD mode 5D3 isn't as sharp as in a 1:1 zoom mode and every bit of sharpness helps, while avoiding extra unsharp mask (which looks weird for FullHD, thanks to debayer - digital bayer) helps with having less noisy image too.
However, I do assume it might be hard to see the difference for not so contrasty image under imperfect conditions.
