Fair question with no real answer. The a6000 is versatile and while the a7R is nice the focusing issues are a deal breaker for an all purpose camera.
I don't buy a lot of equipment and when I do, I want it to be right for me. I've only had 3 cameras in the last 12 years and I'm ready for something new and smaller. My experience with the a6000 just didn't gel and its as simple as that. As a tool it just didn't ever feel right and I didn't want to fight it. I know I could have gotten the job done with it and eventually would have been comfortable with it. Last summer I borrowed a friend's a6000 and had the luxury of spending almost two weeks with it and I just couldn't love it. He even recently offered to sell it to me with 4 lenses for $500 which is beyond generous but I passed and he sold it to another friend who really wanted it. Admittedly what i like is somewhat capricious. I like my cousin's D810 and some friend's Oly OM-D E-M1 cameras and another's Pentax K5IIs is nice. I still love the 5.5 YO a850 and my recently defunct KM 7D. I'm fairly ambivalent regarding all my other friend's cameras and that includes a lot of really nice 'stuff'.
One of the things that overtly disturbed me about the a6000 was that when I was testing some of my a-mount and old Canon FD lenses on it with all manual adaptors, the system flex on a tripod with the a6000/70-300G actually scared me into stopping the testing. I have a pretty solid tripod and a big Sirui ball head and I don't get anywhere near that kind of movement with my a850 and that lens. That wasn't a deal breaker but it certainly gave me pause, especially with borrowed equipment.
I strongly suspect that a FF e-mount camera will be in my future and that will include the LA-EA4 for versatility. The a850 is a better camera than I am a photographer so it doesn't limit my photography in any substantive way, so I'm in no hurry.
