Wire size. Your projects specific needs. Built out time (i.e making your own components). DOM requirements. Licensing. Community. etc. This is an enormous list of variables to determine. If you were not making a complex site or SPA, learning and using React could be huge overkill even though it could still get the job done. The best way to determine what framework or language to use, for me has always been to assemble my tree of needs first. That included things like, how complex are we talking here. Do we need state management? Do we do most of our rendering server side? Do I have to learn the framework? Are the docs good? Etc. Build a map of our own needs first, then spend a few hrs holding it up to the various options.
