@hell OS+DE is Linux Mint and Cinnamon at home, Mac OS at the office. I strongly prefer Linux.
Emacs config is pretty clean and well commented. Some config code is approaching 7 years old now. I feel like I should maybe delete a few things, like some of the Org Mode stuff I no longer use.
The key to a clean init.el is
use-package.@ramin_hal9001 "try to avoid MELPA and install direct from Git repos when I can. My Emacs package manager only installs from ELPA or Non-GNU ELPA."
Genuinely curious. What's the issue/advantage here? Is MELPA unreliable somehow?

@tusharhero But what's the objection to MELPA? Lack of licence requirement? Lack of quality control?
@jameshowell @ramin_hal9001 @hell
1. genuinely a chore to enable it, so I don't want to rely on packages there too much.
2. yeah nonGNU and GNU elpa have a higher guarantee of being free software.
3. Also not a fan of MELPA updating to latest everytime (I think it follows latest commit?) Though there is a melpa stable.
@jameshowell yes, I will confirm that what @tusharhero said is the reason I avoid MELPA. ELPA and NonGNU ELPA are much more stable.
The MELPA packages all pull from GitHub and other public Git forges anyway, and as far as I know, there is no vetting or any attempt to make sure the latest version of a package will play nice with others. That being the case, I prefer to clone the repository myself and install it from my local clone so I can control when it is upgraded. The only problem is that MELPA would take care of dependencies for you, but if a package you are installing has lots of dependencies hosted across various Git repos (as opposed to depending on built-in Emacs packages or NonGNU ELPA packages), it might be a package you should consider not having in your init.el at all.
MELPA might be OK for newer users as a convenience, but I think they should be aware that if they do use MELPA, upgrading external packages can on rare occasions break parts of Emacs if you use it.
Thanks for the thoughtful and thorough reply, @ramin_hal9001. You bring up some issues I had not thought about. Hmmmmm
