I have been quite happy with Obsidian + Tasks.org (synced via nextcloud). I don't connect them in any way. I used TickTick for several years and quite liked it (still recommend it) but at some point they started nerfing the free version and I became more concerned about privacy and supportively of open source so tried a few alternatives and found them to be great. I mostly use Todo list to keep track of things I need to follow up on (like volunteer work) and homework. Unfortunately, I still use Notion for a few things like Wikipedia page ideas because I simply don't like the way "databases" feel to edit in Obsidian with the available plugins. Obsidian for me is mostly a daily journal plus a few pages that are like notes about cities I visited or my thoughts on the language learning apps I've experimented with.
