Newer 5.2s are apparently rock solid. I believe it's the 2018 and beyond gt350s that fixed most of the issues.
They're marginally better. There was a big fuss back when the Gen 2 voodoos came out and people were still reporting infantile failures and oil consumption issues.

That is correct and unfortunately it’s due to ford using a firing order that creates a rocking couple. And unfortunately there is absolutely nothing you can do about it other than hope you got an engine that’s balanced happily from the factory

Apparently something about the existence of the dual air intakes on the s650 means if they were to make a new flat plane, the vibration and balancing issues shouldn't be as much of a problem, if at all.

So fingers crossed some sort of 5.4 flat plane wouldn't have all those issues.

That’s correct they could and would use a traditional FPC firing order. Ford last time around said they couldn’t package a twin throttle body setup under the GT350s hood because it was lowered by 20mms. This time around it’s very apparent they wanted to move past that limitation, whether or not we see a real next gen GT350 is up for debate. But as it sits today this would fix the vast majority of the 5.2 NVh issues

I don't know if we'll see a return of the gt350 name, but it seems like whatever this road going version of the gt3 car is will be the gt350 equivalent of this gen.
