People should use with whatever they feel comfortable with, but I personally don't see the advantage. I used VSCode once for simple edits of something and it worked, but I couldn't imagine really using it for a project due to the lack of… everything. The whole support of the JetBrains products from the smart autocompletion, pointing out errors in advance, to improving your code, is insane, and with VSCode, you don't have that.
I also once had a small project with two people using PyCharm and one VSCode and the differences in the code style were insane. Of course that depends on the person, but it's just much easier to obey all the style guidelines and write cleaner code with the former one.
