I had the 5N and now have the 6. AF improvement is minor. It went from unusable in many situations, to acceptable, at best.
I shot a GX-1 for 7 months before that (and many DLSRs before, the latest being a D700, so I know what pro level AF acts like). The GX-1 was very, very competent for static or slow moving subjects, even in super dim light, AND very accurate (I read several reports the E-M5 is blazing fast in daylight, but tends to hunt in low light and can mis focus quite a bit).
When I got the 5N the AF was so slow I just switched to manual focus entirely.
The 6 isn't that much better that I want to use AF with it either. So far my NEX's are MF cameras.
