Vue should be a bit faster due to signals (updating state doesn't cause whole components to rerender), or at least require a bit less work to optimize (not as much need for useMemo, useEffect, etc. if everything uses signals). Other than that, it's mostly up to personal preference. SFC, directives, etc. are all just developer ergonomics, and people tend to prefer whatever they're most used to.
Also, vue interops better with webcomponents and non-framework code than React in my experience. Most non-React libraries need a React wrapper to work in a React project.
