For me, not needing another app and the fact that is easily selfhosted is great. For Obsidian you have to pay for their sync solution and I remember the logseq app was cumbersome and the web client wasn't so good, but that's my opinion.

I've been using silverbullet for a while. Selfhosted, saves everything on simple markdown files and easy to customize with plugins and space scripts.

I use QuickWeather and use the Open-Meteo integration. You can even selfhost it for better privacy probably.
