Yes. In general, I would choose Scala. Better tooling, (pretty good) type system; not without its warts. Main concern I'd see ahead is the 2 -> 3 transition, which has the potential to be as difficult as the Python 2 -> 3 transition. That said, Scala 3 looks nicer to me as a language, with top-level functions, significant whitespace (more concise code), and better ADTs.
