Compared to the turntable-based disc machines, what unique benefit did the cylinder’s axial recording stylus movement offer early users?

Answer

It lent itself better to early mobile use for field reporting.

Because the recording stylus moved axially (along the length of the cylinder), the phonograph form factor was sometimes more conducive to being made relatively portable for field use.
