Seems solid, although I think it’s safe to say for the core function it doesnt look as powerful as word (which is fair since most people don’t need that) and it does seem to have nice add-ons like graphs and code blocks.

I would be cautious about using a markdown editor and assuming it’s cross-compatible. Core markdown is shockingly limited, and every other flavor seems just a little bit different from one another. Whether it’s how they do code blocks, or how they add other functions, there’s always something. But as long as you’re not switching between tools that’s no risk.
