The best camera is one that still works!
The nice thing is you can select the position of the focus point (with both cameras) so it does not have to affect your composition.
I tend not to stare at the dot, but focus using the screen and happen to notice when the dot appears.
Slightly off topic.. manually focusing with a Nikon F6 is far superior to any DLSR that I have used, even though the F6 is also an AF camera. Nikon really spent the time on that one to make sure it works perfectly with both types of lenses.
Yes that's it ... you don't have to stare at the dot, just concentrate on composition and visual focus and you usually become aware the instant the dot lights up.
