It's more complicated than just rolling shutter. Using the electronic shutter removes most of the dynamic range advantage over the a7rV. Also, due to the slowish readout speed, LED banding is much more likely to be an issue, and flash sync speeds are greatly reduced.
I am sure there are still some use cases where the electronic shutter at 30 FPS will be nice to have, but personally I feel like if I pick up the a7rVI I am going to end up using it most of the time with the mechanical shutter.
Yes, suprisingly there still is one stop of dynamic range difference between electronic and mechanical shutter on the Sony A7RVI.
Actually the difference is very minimal in the original A1 (according to DPReview).
Interestingly, even with electronic shutter the dynamic range of the A7RVI is still better than that of the Nikon Z8/Z9.

The a7rV to a7rVI jump isn't that tempting, but the Z8 to a7rVI definitely is.
Not to forget the clearly better dynamic range of at least a stop of the A7RVI versus the Z8/9 with mechanical shutter.
(Which the Z8/9 unfortunately does not have).
I know Scott is a Nikon fanboy regularly lurking on these Sony pages, he won‘t like to hear this.

The sync speed is 1/250th, maybe lower with large strobes. That's rather standard. Am I not understanding the issue?
EBH
My understanding is that is only when using the mechanical shutter:
Flash sync is also limited on the a7R VI. The sync speed is 1/250, compared to 1/400 on the a1 II. More significantly, flash will not work at all when using the electronic shutter on the a7R VI, while the a1 II allows flash sync up to 1/200 with the electronic shutter.

Something to keep in mind is that the Z8/Z9 has a base ISO of 64, while the a7rVI/a1ii uses a base ISO of 100.
At low ISO 100, Sony is about .8 of a stop ahead of Nikon, but compare Sony ISO 100 to Nikon ISO 64, and Sony is ahead by about .1 of a stop. Once we get to ISO 800, Sony keeps about .4 of a stop ahead of Nikon.
Depending on your usage, you may find ISO 64 worth the hit in dynamic range, or you might find it an annoying trade off.
