I've been really happy with Logseq. It has a similar interface to Reflect by the looks of it, but it saves to the local file system in plain text (markdown-ish) format. They have sync now, but roll your own sync via git is also very feasible. Obsidian is similar but I like the 'outliner' 'Roam like' apps that can infer relationships via blocks and indentation.
Logseq is well done. I ended up using it for about a month but then went to Obsidian -- I ended up realizing I like to use outliner mode for certain types of notes, but found Obsidian to be better for straight writing. There's an outliner plugin for Obsidian that gets you close-ish to Logseq and other outlners, but I ended up detuning its settings to just make bulleted lists better. Totally recommend checking out Logseq though, it's good software.
Yeah agree Obsidian is better for long form. You can change the enter key behaviour so on it's own it doesn't create a new block, but small blocks works better for my note taking style.
