In my testing the Samsung S34E790C actually had superior motion clarity overall than the Dell U3415W. So I certainly look forward to the upcoming
C34F791WD. There are indeed some weaknesses with some pixel responsiveness (as is always the case for VA) but it is unlike any other VA model on the market for overall pixel responsiveness. The C3583FQ is simply nowhere near achieving such a good balance - despite the refresh rate increase, the pixel responsiveness is noticeably worse than on the Samsung. And I wouldn't say that they all have problems with 'noticeable banding'. In most cases it's simply that people are observing banded source images so the monitor simply displays that correctly. Yes there is what I would call fairly minor banding in places, but that's not exclusive to VA panels nor is it something most users should have an issue with.
