Emacs comes with extensive documentation. "C-h t" opens an interactive tutorial that teaches the basics, "C-h r" opens the manual. "C-h i" opens the Texinfo browser that gives you access to even more documentation, including manuals for Emacs Lisp and Magit (if installed).
The learning curve is fairly steep in the beginning, but after ~15 years, I feel that the initial effort has paid off a lot. Not everyone likes emacs, and that's okay. But I do think it is worth giving it a try and seeing for yourself.
(As for the whole vi-vs-emacs debate, I have used both over time, and I do use vi quite regularly for quickly editing some config file. There are packages for emacs, like evil-mode, that emulate vi's key bindings and behavior, but I have not tried any of them.)
