I completely agree, but I would wager that VS Code would still be noticeably faster even if it had all of the functionality that IntelliJ does. As a daily user of the latter, it seems like they have a lot more room for optimization, whereas VS Code seems to have been built from day 1 with performance in mind. But this is pure anecdote so I could be wrong.
