I don't use Visual Studio Code. I have no experience.

I stumbled upon this question right now. I have been extensively using Emacs+AucTeX for the last 4 years and switched to VSCode in September. I am doing extremely fine with the LaTeX Workshop extension and I think is a viable replacement for my previous toolkit.

With respect to Emacs+AucTeX, it lacks the quick navigation that could be provided with RefTeX, but it has many other pros, first of all being within an environment which is extremely friendly still being very lightweight.

So, it is totally a viable option, IMVHO.
