far better option than notion, onenote, etc for most people

OK.

be fairly easy to get the important data migrated into anything else.

Why bother when I can do it now with the better option rather than in a couple years with several thousand notes?

Also it should be noted that peculiarities about how obsidian works makes transfers non trivial. Individual notes are fine, file structures not as much, but it's minor.

Trilium has a pretty robust export system last I checked. Not rally worried about that, meanwhile I get the massive speed upgrades and stability associated with a database.

Sure it could be reverse engineered... Or just use the software that's already basically there...

You're doing that thing where someone starts going to bat and listing off this that or this other thing to rationalize their own choice or rationalize the choice for others.

I've used obsidian for years. I switched to trilium for reasons I stated above. Unless obsidian goes fully foss, and gets way way more stable, i'll be using the genuinely better choice, thanks though.
