I've historically had a rather shaky relationship with Notion, I've always found that it's trying to do too much and that I would just get completely lost in the app and it would just make me less productive overall
Now that I've got so much stuff going on between the blogs, my business, personal stuff, and (soon) a new job, it's gotten really chaotic to manage across disparate apps
I'd have trouble keeping Trello and Obsidian in sync, I'd have issues syncing all of that with my calendars, etc
