I use both, while Obsidian is good and has lot in common but for some reason org-mode still feels more useful and permanent. If it something important for me personally I most likely will put it in 'org' but if I just need write something of temporary nature like documentation peace for work I might prefer Obsidian for that. Also org-mode TODOs/agenda stuff very helpful for triage of tasks and prioritization (I think it's just habit that has some 'migration' cost so I not really considering it as big benefit over other tools)
