Sometimes it is nice to have a separate application for notes compared to the editor being used for code. It means they can be customized for their individual purposes. Sometimes there are minor inconveniences (I miss multi-select/change in Obsidian sometimes), but even when I used an editor for my MD notes, I found myself using SublimeText for that while I used VSCode or IntelliJ for coding. Just a 1 of 1 experience, but as mentioned elsewhere, there is a large adoption of note taking apps separate from code editors, and a few of them use markdown as the underlying file type which I require for anything I use for portability.
