E-mount lenses focus more accurately than A-mount lenses?

I bought the LA-EA2 and a couple lenses a while a ago, and took pictures with them for several occasions. When I viewed them at 100% however few photos appeared to be slightly off focus. I thought it was a back/front focus issue where I'd need microadjustment but on other photos the same lens/FL/aperture/etc produce focused pictures.

This never happens to me with E-mount lenses; if I chose the point I want to focus and all the right settings, then it'll focus spot on (despite being slower and sometimes not having enough light to focus at all).

So I was wondering if this a difference between CDAF & PDAF, in that CDAF will focus spot when correctly focused and that no matter what you do PDAF may still slightly misfocus at times?
