Direct answer
For reference-based work, “best” means the system preserves the parts you need while changing the intended parts. Test identity, composition, text, aspect ratio, reference count, edit controls and export rights with a small controlled set.
Search volume is an observed demand signal; it does not prove that a tool is best, free, available in every region or suitable for a project.
