I used to use both obsidian and logseq the rich text of trilium isn't that rich it is practically markdown but made simpler with a menu, more like the obsidian mobile app. Practically trilium isn't strictly hierarchy based, if you wanted you could just slap everything in one folder and link what you want. The clone feature comes handy form people like me that have to have everything neatly organized so if I want a note in 2 folders at the same time I can do that. Sadly the [[link]] format isn't supported as of now but it has its own internal linking, just press ctrl+L and link away. I hope this helps, maybe it's not the perfect option for you but I would love if you could spread the word, Thank you very much
