I wouldn't necessarily go by what's posted here as it's all going to be mangled by the posting process to some degree. Things may be different when you're looking at a full sized picture at home. Any increase in image quality is welcome but the making things easier bit is attractive and as I keep saying stuff like face detect make it possible to take pictures that couldn't have been taken before, not without stopping the lens down or asking the subject to freeze while I focus manually or move the focus point.
I took this a few weeks ago and it's now framed at home, it's just a moment in time but I couldn't have taken this picture with anything other than a mirrorless camera with at least face detect...
I have a lot of pictures like that now and I like that one of Mrs WW emptying the birdseed bag too.
Before I started using fact detect the only way I could take a picture of someone without getting them to pose would be to prefocus or let a smaller aperture cover movement with DoF. You can shoot quickly with a manual lens...
But that only works at smaller apertures like f5.6/8 so that the DoF covers any movement. Try it at f1.8-2.8 and chances are you'll be off.
The new kit with bells and whistles just adds other abilities.
