That depends. I have a split prism screen in my D200 and find that
manually focusing is more accurate if I am not tired, provided I use a
lens with a reasonably long focus throw. For example, with a manual
focus 28mm lens I have I get good accuracy and repeatability, while
with a tamron 17-50mm which I also have it's practically impossible to
focus reliably because of the short throw of the focus ring (and the
fact that it has some play).

Of course autofocus doesn't get tired and works at lower light levels
than I can focus in. It's also much faster than me. So both systems
have advantages. And certainly autofocus is good enough for most
things, and the only way for some.
