Alessandro, this is what I have experienced.
There are three possibilities:
#1 manually focussed completely wrong (happens rarely)
#2 AF, seems to be sharp but at 100% magnification you can see that it's not
#3 manually focussed and spot on

#2 so true in my experience.
AF gives only approximation of precise focus. In my personal experience, I am not getting more precise focused shots with AF. They are the same percentage of MF, or even less. With the difference that at least MF shots (when taken with good lenses) are more useable even if not perfectly focused. Instead, an AF shot that is not perfectly focused, is nearly useless, because the image looks so weak.
I'd add that for me, #3 does not happen more often than #1
I think at least 80% of my AF shots fall into the #2 category.

Yes Orio,let's add
#2.5 MF, still not spot on but much more usable than #2
I think Alessandro said something very important, it's a matter of practicing.
Something I did, by strictly using my three main lenses, to get used to them.

Don't expect too much from a split focusing screen. I prefer a fast matte screen like the EE-S, the sharpness will pop into your eye, all over the viewfinder.
With a split screen the usual routine is: center the object and focus with your split screen, then compose or recompose and shoot. But during the recompose you will loose the focus.
A bright matte screen allows me to compose and focus on the same time.

This turned into an interesting discussion.

In fact, before I got mf lenses, I had the some problem, when using fast AF primes, like the Canon 50mm f/1.4 USM.
Well, what I can say is that my 35mm L is just perfectly calibrated with my 5D Mark II. I tried to take a shot with it, using manual focus with live view and, after that, I took another using AF. Of course the camera was mounted on a tripod for both shots. The result was exactly the same at f/1.4, which proves the AF couldn't be more accurate.
I know this lens has a great reputation, but I think I found an incredible copy.
I did a test comparing it with a Canon 16-35mm f/2.8 L (MK1). Of course I was expecting the prime to be a lot better but - you believe it or not - I wasn't expecting it to be sharper (I just tested the center) at f/1.4, than the zoom at f/5.6! 
Seriously, I just couldn't believe.
I found another interesting thing. The Zeiss is a true 35mm and it offers the same exact field of view as the 16-35mm at 35mm. The Canon happens to be much wider, probably around 32mm.
Unfortunately I can't afford the 24mm f/1.4 L MK II, which has an amazing reputation. All the reviews say brilliant things about it and I'm sure it has to be one of the best wide angles available. Probably it's close (not as good) to the legendary Zeiss Distagon T* 21mm f/2.8.
Anyway, I'll have to go with the first version. I don't expect it to be as good as the Zeiss "Hollywood", especially in the corners, but I'm really tempted by the aperture. Since I rarely shoot landscapes, I believe the Canon is more useful to me for the kind of situations I already mentioned before.
About the 50mm, there's no way I would trade my Planar T* f/1.4 for the Canon 50mm f/1.4. I used to have one and I think the Zeiss is really much better. The Canon 50mm f/1.2 L is tempting, but it's the kind of lens I think I would never buy, because it's too expensive and I doubt it's sharper than the Zeiss.

Believe me, I have a lot of practice using mf lenses. 
However there's no way we can be as fast as a calibrated AF USM lens.

This is true and it's a problem some people find with AF lenses when they don't change the AF point. Using extreme apertures, the slightest movement to recompose will result in a out of focus shot.

Thank you! But it's far from beeing complete, still missing the famous 1.4/35

It depends, when you use fast lenses wide open you have to switch around the focus point and it's not that faster than turning the focus on a MF lens, actually I find it a lot slower with a higher risk to miss the image I want.
If you use lenses stopped down a bit instead you have a safety margin depending on the distance from the subject, the focal length of the lens and the f-stop you use. Just to say photoreporter of the past used often a 28 mm at f8 and just cared about shutter time without worrying about focus, you have to put some efforts in not getting good focus on a subject using a 28mm at f8 (I don't talk about landscapes of course).
When I really had problems with MF was that I had good focus in the screen and it was missed in the image. I boggled at it for a while since when I took out my glasses and used contact lenses. Problem solved

| Contax lenses are just amazing. I just got a 35 1.4 on it's way. I hope to get a 28 f2, 85 f1.4 as well. The 1.2s are amazing but just not affordable. |

Using the David's thread I have to say I got the Distagon 35/1.4 and Makro Planar 100/2.8.
Unfortunally I don't know why but the Distagon doesn't close the blades when mounted on the 5D. If I hit the lens with my finger from the side he closes to the aperture I choosed but if I open they blades become stuck again...
Outside of the camera the blades open and close without any problem...
I think the problem is the adaptor...
I didn't test it yet because of that...I only did some shoots with RTSIII but I didn't finish the film yet...
I talk a lot with David about these amazing lenses and we really love them but I understand why David is using some AF lenses as 35/1.4L...For his kind of photography is necessary...

Thanks, Ivo!
The 35mm is comig back, since Jan found a 2mm soft scratch on the back element, that I've never noticed. He did some tests and can say the performance still perfect, as expected, however he's looking for a mint copy.
It'll be for sale again, this time with a discount.
qqbingbing,
I have a Distagon 28mm f/2.0 for sale. You can find it in this section of the forum.

That would be a good time to sell mine, since it is really perfect with the leather bag... But I don't know if I want to sell it...
I don't know if I sell the Makro-Planar or the Distagon...
Both have the same value and I don't know wich one I'd use more. The Makro-Planar could be good to Beauty shots but I can get good results with a cheaper macro lens too...
Distagon is more exotic and it is not easy to get a mint copy like this one...
I really don't know what to do...
