Ruby Installers and Ruby Switchers

In this post I review the most popular Ruby installers (making it easier to install a Ruby) and Ruby switchers (to switch between different Rubies conveniently).I contributed to all 3 Ruby installers when adding support for TruffleRuby, and so I have experience both with their codebase and their usage.I am not reviewing Ruby installers or switchers for Windows as I have no experience with them.TLDR: feel free to jump to the Conclusion and Recommendation.Ruby Installers.
