I persevered this time because I really want to use libre software wherever possible. Emacs must be one of the longest running free software projects out there, and I feel it will exist for a long time after other editors have come and gone. It is really hackable and has a great community of people hacking on it.
I would never make the claim that Emacs is better than any other editor, there are many good ones out there, and I think it really depends on what you want and why. But I can quite definitely say that after using emacs regularly for a few years, I absolutely love it, and can’t imagine myself using anything else anytime soon.
I can’t recommend a good tutorial as I never really did one end-to-end, just dipped into different things here and there.
Bit I think series of short videos can be better than text tutorials for this, sometimes.
I haven’t watched this series, Using Emacs, but I see it linked a lot, so it might be useful: https://www.youtube.com/watch?v=49kBWM3RQQ8&list=PL9KxKa8NpFxIcNQa9js7dQQIHc81b0-Xg
This one is quite good for org-mode, not least because he sounds like Arnold Schwarzenegger: https://www.youtube.com/watch?v=sQS06Qjnkcc
