The other thing about peaking, in my view, is that it takes over your viewfinder and distracts from what you are seeing. You can use the low setting, but often it's not enough. Use more and the peaking intrudes on the scene and blocks fine detail of your subject, such as expressions and gestures.
I agree that magnification is better, but for fast street work neither works particularly well. I find zone focusing or a good AF system to be much better. If I still had an A7, that's the direction I would take for street shooting.
With wide-ish lenses and stopped down to f/5.6-f/11, sure: zone focus works great. And I agree about the distraction that peaking presents ... I wish there was a way to get a one-button press to turn it on and off; there isn't with the A7/A7r.
But once I'm up to 40-50mm or so, and especially if I'm running wider than f/4 as the focus zone, I prefer to focus as the focus zone becomes too shallow. For 40-50mm at f/2.8-f/4, I can focus to acceptably sharp in an instant manually with the A7 without using either peaking or focus assist magnification.
EXCEPT in very bright circumstances outdoors: the A7's EVF brightness does not ramp up high enough to handle the influence of very bright sun for me unless I am using a wide-brim hat to shade my face and the camera. This is most likely because of the fact that I wear glasses and can't easily block the sun from spilling around the side and across my eye. (I have the same problem with optical finders, it's not an EVF only issue ...) Then I often trigger magnification so that I can get a glimpse of the sharpness in my focal plane more effectively, but of course that's also when I can just stop down to f/11 and focus by zone more easily.
For some reason, the Olympus E-M1 EVF does better in this circumstance. I think its sunlight adaptation range is larger and the controlling software/optics are better.
