I'm new-ish to Ruby and Rails. I am looking for a purely objective list of features and advantages/disadvantages of each. In an effort to keep preference out of this, please refrain from answering unless you have used all 3 systems.
There's three main options available today:
rbenv
.Personally I prefer rbenv
because it works well with Homebrew and doesn't mangle the shell environment as much, but tend to use rvm
on servers where that doesn't matter because they're set up for a very specific purpose.
