I've been using Reflect for a few months now. Prior to this, I've used Roam, Obsidian, Logseq, Evernote, and Apple Notes at various times.
Reflect is fast, intuitive, and it's clear the team is thoughtful about the details. This is now my primary note taking took.
The only downside I've noticed so far is a lack of any collaborative features (thanks to e2e encryption). But since my main use case is just as my private brain anyway, it's not a big deal (and would argue it's a feature).
