I use Obsidian for that exact reason of the notebook being "just" a collection of raw markdown files and owning my own data as well. I'm pretty happy with it so far. I still use Sublime to edit the files quickly and when I don't need features provided by Obsidian plugins. A minor gripe is that the iCloud sync is really really bad. Perhaps that's more on Apple than Obsidian, but frequently editing of the same files across multiple devices is a pain point today. To their credit, they have acknowledged this and now offer their own first-party sync service, but I think $96/year to sync a folder of Markdown files from my laptop to my phone is excessive.
