Gyro stabilization in my testing is better than in-camera stabilization and post stabilization but the workflow is still a pain. Both Gyroflow and Catalyst have limitations and annoyances, so most often than not I rely on in-camera stabilization.

Not surprising for $3500 toy. It's cool and all but there's nothing unique about it to justify owning it.
ZF probably makes more sense than Z6II or Z7II because of internal N-LOG but the handling is way worse. I wouldn't use it for video because of it. Looks great though.
