I decided to start note taking with VimWiki. It's organization is the same and has full vim support where Obsidian has partial keybindings. I still feel like I'm missing out. Can anyone opine on if it's worth switching over?
Don't fall for the trap of note taking tools. At the end of the day, if you can write down your thoughts then it does the job. Spend less time on thinking about tools and more time on writing notes.
At the same time, in my opinion you should feel comfortable in your tool. If VimWiki does not suit your needs but you still want to use vim (like I do), you could look into https://github.com/epwalsh/obsidian.nvim to edit notes in neovim, and then view them in Obsidian using :ObsidianOpen. I like to have my terminal and Obsidian open side-by-side for this workflow.
