I tried VScode twice and despise it. Cold never get it to be much more useful than a text editor with syntax highlighting. Tried setting it up for java and even with fiddling and tweaking it didn't work nearly as well as the default eclipse setup regarding code navigation and maven integration. It felt just like trying to get vim to be modern and useful. Maybe possible, but a lot of effort when there is other solutions that work right out of the box. Second try was for PHP, and that was even more futile. For PHP it actually seems like jetbrains is the only one providing an ide that doesn't make you lose your mind with that language, so not necessarily a sign that VScode in particular is bad.

For C++ I never even tried it because I'm usually content with qt creator.
