I've only used nvm so far (it was enough effort to get the team to adopt one such tool, and nvm was the main one at the time), but as far as I can see the main differences are speed, native Windows support, and being able to specify both the Node and npm/Yarn versions — that latter point is an important part in getting reproducible results across machines as well. Additionally, at least nvm does encourage pinning to a major version, allowing people's minor/patch versions still to diverge. (The upside I suppose is that that can save you quite a bit of disk space with relatively manageable risks.)
