What's the difference between the DJI RS 4 and RS 5?

Across the reviewers we read, the RS 5 is positioned as the newer flagship with more torque, an electronic briefcase handle, and updated touchscreen tracking, while the RS 4 remains the established workhorse with broader long-term review coverage and a typically lower price. The RS 4 is the safer mature buy; the RS 5 is the upgrade pick for heavier rigs.
