I love VSC but let's be frank, on a N2940 cpu with 4GB of RAM, there is no debate as to what editor is faster and less memory hungry, Sublime Text is.

I just started with the whole asp.net core thing though and so far the experience has been really great when working with C# and Typescript. Better than with ST. So now it's VSC for .net dev on linux and emacs for the rest.
