Nice, I second VSCode, although I have always a VIM version for the quick edits installed.
I just checked the website for xanmod and it looks interesting, several questions:
Do you really use it on a desktop? (The website seems to suggest it is optimized for server loads)
How exactly do you experience the difference in performance?
What is your most low tech computer you run xanmod on? (I simply heard too many times, that nowadays there is no good reason to compile your own kernel unless you have very specific needs.)
