Dave, I have the E or Cropped Sensor version, or the Sony 50mm f/1.8 OSS lens. I have no experience with the FE or full frame version but, from my research, I suspect that the crop sensor model produces slightly better image quality than the full frame or FE version. I think that the image quality of my lens is just fine and the Eye-AF is amazing. The crop sensor lens has OSS which should help with your A6000 since that camera doesn't have IBIS. The wide open f/1.8 aperture really blurs the background.. I purchased the lens used at less than $200 USD...
Here are some images that I shot wide open with my A6500 and the OSS lens...
1. ISO 400
2. ISO 320
3. ISO 320
The EYE AF really nailed the focus on the subjects eyes. It is fun to use and so easy that it seems like cheating. (but, that's what I thought when I first used autofocus lenses). No focus and recompose needed. I have experimented placing the subjects eyes in any part of the frame and Eye AF consistently nails the focus.
For these shots, I used aperture priority, continuous focus, wide focus area, and Eye-AF which I set up for the AEL Button. I first tried using the rear center button for Eye AF but, that button was not convenient so I switched the Eye AF to the AEL button which is closer to the shutter release button.
My next shot will include fill flash with a Godox tt865S on a bracket and Godox Pro trigger...
