Nothing ground shattering and yet we are all going goo goo over the new Fuji. I would think this A73 stacks up very well against the Fuji, surpassing it in many areas especially in eye AF tracking.
If anything I would call Kevin more a Sony fanboy than Fuji, I think these days he mostly shoots with Sony.
I do agree that for somebody starting fresh the A7iii sounds more compelling than X-H1. I do think however that the difference will be made in lenses/ ecosystem. On a side note I find funny that the X-H1 seems to have better video specs, this coming from somebody who rarely uses video though. One place where Fuji screwed up with the X-H1 is when they kept the same battery size despite increasing the grip.
Obviously if those sensor artifacts are common then it's a different story. All mirrorless seem to have some similar issues (despite claims of them being so much better than DSLRs) but at least on my Fuji is not that common. I did see it during my recent trip to Iceland more than once though, ruined a couple of shots. I don't recall seeing it on my E-M5ii but I use it less often.
