Used TheBrain since 2008. Now a convert to Obsidian. The rate of development with TheBrain has been very slow whereas Obsidian is on warp speed.
Big pro’s for Obsidian IMHO are
- Non-proprietary storage.
- Price
- Rate of Development
The only problem is I have circa 13k of thoughts to get through over the coming years to transfer my IP out of TheBrain to Obsidian.
Will always have a soft spot for TheBrain but have used it too much as a collection tool rather than a PKM so Obsidian has come around at an opportune time for me.
