The great thing about Obsidian is that it still uses plaintext (it's not obsidian exclusive, i know). In case of issues with the tool, you can view and edit files in an editor. It also makes syncing stuff / backups very easy. Since you're probably having a kind of syntax already it won't be hard to change.

With a proper keyboard, it's super fast to create and link notes. On mobile it sucks hard. Things like "[text](linkForText)" are not very mobile-friendly.

One big gripe i have is the table editor. There is an advanced table add-in to help, but it still sucks. Create a table and put a long link into it.

Well-known keys like "end" or "pos1" don't do the expected. "TAB" will add fields... i don't know, this should be better.
