I’m exactly the same! Starting paying for Notion once I’d received the value upfront and felt like paying was worth it.

Dropbox - still on free after getting lots of free space through promos

Spotify - family account

GitHub - paid for personal until the recent change

My takeaway, none of these freemium methods are “bad” but Notion felt the best as a consumer. I talk about Notion way more than the others and I believe their pricing model makes that possible
