The short answer is yes, but it does depend on the type of shot. For landscapes, I routinely hyperfocus if using my 24-70 or 17-35, and so dont need to look through the viewfinder to judge focal plane at all. I know that at f16 or f11 respectively I will have front to back sharpness with these lenses and apetures.
If using a 70-200, I do need to check focal plane and depth of field. This is definately easier to do using live view on the 7D than through the view finder on the 1Ds11, but I havent found using AF to be more accurate for landscape work.
Macro - again manual focus if a must, and again live view makes this much easier.
The only time AF is definately superior is where I need to focus fast e.g. shooting birds/wildlife or candid shots of my kids.
