My guess is none of them will ever replace Node.js, but they will all help shift the momentum of Node.js to be faster, better support for Typescript, etc. Similar to how folks created io.js at one point and that eventually got merged back into Node.js. Deno seems like to offer a better dev experience, and because it's created by Dahl it's the only one I take seriously as an alternative.
