It is just that after some practice, magnification gave me the sharpness
exactly where I wanted it, and focus peaking didn't. It is also less
usefull on m43, and I think my e-m5 doesn't have it at all, so I kind of
standardized on magnification as my default MF workflow.

But you milage may vary of course. Good to have options.
