Opinions? From A7Riii to a9? Or A7iv?

So here's a non conventional question: I have been using the A7RIII for a year now (bought second hand in excellent condition) and I'm mostly very happy about it. I was using the a7iii before and I upgraded for the better Evf and screen (yep, those were my main issues with the A7iii). However, I discovered I really like that 42mpix sensor! The images coming from it are stunning!

So what am I missing? Well... Two friends of mine just got an A7iv and I must say that the autofocus does seem quite a bit better. When shooting in the studio, I sometimes get slightly misfocused eyes with my A7Riii. On moving subjects (kids playing etc), the keeper rate is ok but not stellar.

Fast forward a few weeks, and I have the opportunity to get an original Sony A9 (my dream camera a few years back) for about 2000€. That is 600€ less than a A7iv. Problem is: I can't afford to keep both the A7RIII and the A9.  But in a pinch, I could afford a A7iv.

Now the question is: how much better is the AF on the A7iv compared to the A7RIII? And how does it compare to the A9? Is there really a big difference?

Also, I loved the A7iii files and honestly, I almost never make prints so the 42 megapixels are probably overkill much of the time. The idea of shooting with electronic shutter all the time without distortion and having a top notch AF for more keepers is attractive too. Maybe that's all I need  🤔🤣

For info, I am using mainly Tamron lenses ( the 2.8 trinity) as well as Samyang primes. The only Sony lens I have is the 85 1.8. The 28-75 is giving me the worse AF performance, maybe it's time to upgrade the lens?

Any thoughts would be appreciated 👍
