One of my personal role models, https://github.com/Gabriel439/, uses mostly vanilla Vim. Maybe they'd be 10x as productive with an IDE, but I doubt it. And in any case, the difference in quality and output between them and me is certainly not the tools.
I don't think the tooling matters at all, unless you work in a very specific field where certain tools may be mandatory.
Whether you look up APIs in documentation or read that same documentation in your editor, who cares? Seeing red squiggles as you type or in a terminal window that refreshes on change? Who cares. It wouldn't even make a difference if you only saw errors when manually starting compilation.

None of it really matters in the end.
