Used v3 a few years ago at Linode and it was ok, if overly complex. The API changes resulting in v4 were so great that it basically became an entirely new project -- and the v4 docs are _still_ incomplete/not very helpful. Faced with learning a new project anyway I went with router5 at Capsule8. Not only is router5's API simple, well-documented and easily programmable, the router5 folks have been receptive to feedback and pull requests. They also keep fairly well up-to-date compared to react-router (router5 supports React hooks, react-router doesn't yet). I'm content with the direction and design of router5 and encourage others to check it out.
