For me, it definitely adds something to the conversation. I simply much prefer native apps to Electron-based apps, and I'm not the only one. The original comment thus saves me time.
For obsidian it is a significant advantage because you can have plugins that e.g. render a markdown task lists as a Kanban board.
It seems to fall into the vs-code category of being sufficiently well optimized, but if you wanted to deal with millions of files then some popular plugins (queries on tasklists in all files, aggregating data into diagrams, etc) probably would get slow.
