i would agree with this statement for most conventional shots.
overall, i am still thinking that a ballhead will be better - i found it immensely hard to angle the camera downwards (extreme) in the vertical position easily with my giottos pantilthead.. and shooting upwards into the sky was also impossible because of the limitations of that particular pantilthead.
of course, if there are pantiltheads that manage to overcome this, then please ignore this statement.
