It has some advantages and some disadvantages with respect to autofocus. 
Autofocus is often clearly faster, but focus peaking works over the whole 
screen, and you are often more certain about what will actually be in focus. 
Certainly the Fuji has an issue with the latter in my experience which is 
admittedly rather small. For critical focussing a highly magnified live view 
is stlll more accurate than either. 

Focus peaking is something that appeals strongly to me, as you have full 
control over what will be in focus and you have independence of optical 
characteristics and mechanical tolerances. I don't actually have that much 
trouble getting sharp, in focus pictures with the 75 Summilux, but I too 
will admit that my hit rate would almost certainly be improved both with it 
and the Noctilux if focus peaking is implemented well, and works properly in 
low light where I'll be shooting at full aperture.
