So 10 hours on a config is only .5%, which is the productivity gain you need to realise to get that time back in one year (assuming you also spend 0 hours on fighting vscode).
Unless you're retiring within the year, that calculus doesn't make sense.
The productivity boost you get with from Emacs/vim is huge once you learn it well.
I strongly believe that learning one of these two editors is probably the easiest and biggest skills leap you can take as an intermediate or senior developer.
No other skill you can learn will have as big of a payoff to your productivity given the relatively small effort to get proficient.
