I forgot to mention one other thing about tree-sitter: the error recovery/tolerance, which is a requirement for practical parsing applications. It does an excellent job of returning a parse tree even if the text contains tons of errors. Instaparse, besides being much slower, just gave up if a single character was out of place. Super rarely there will be an error that causes tree-sitter to fail more comprehensively, but it is one of the few parser frameworks that even tries.
