Dpreview claims the Sony ZV-E10 still has the edge over the Nikon Z30

Dpreview compared the two cameras and came to the following conclusion:

The Sony ZV-E10 and Nikon Z30 are very similar cameras in many respects, which makes it a little hard to choose between them.

If we were primarily shooting stills, we’d probably opt for the Nikon. The better kit zoom and smoother sharing experience with Snapbridge definitely count in its favor, as does its front-and-rear dial control setup. Its full-width video if you want 4K/30 is also a distinct advantage.
However, the Sony’s better battery life, the inclusion of a headphone socket, and the much wider choice of lenses are all compelling benefits, if you plan to move beyond using the 16-50mm power zoom. It exhibits a lot of rolling shutter effect in video, which is a major black mark against it. But it’s the ZV-E10’s autofocus that gives it the edge for us. It’s easier and quicker to use when shooting stills and that bit more reliable when shooting video, and we don’t think the Nikon has enough to counter that.
