For static subjects (products, landscapes, PCBs, flat stock), yes—live view axis control is objectively superior to optical methods. For fast action (sports, running CNC tools), the latency of live view hurts you.
The "Best" Workflow:
Before pressing the shutter or hitting record, you must understand the three axes your live view represents:
The Best Practice: Zero your axes before you compose. Most high-end cameras and tripod heads feature electronic levels or artificial horizons. In live view, overlay this level. If your camera lacks it, use a hot-shoe bubble level. The "best" live view axis begins with the sensor being physically orthogonal to gravity (for landscapes) or parallel to the subject (for reproduction work).
