+1. I remember checking out Standard Notes and their longevity mission is very positive. They seem to have a solid product, but their approach just doesn't click for me.

Been using Joplin for a couple years. It's one of those few open-source apps that managed to find a golden ratio of functionality but still to the point, a coherent pleasant experience across desktop and mobile.

Missing a basic collab or note sharing functionality though. It's all open formats and that, sure one could hack around it, but more in the spirit of mutual access to encrypted notebooks for example.
