For me, the speed of rendering is fantastic.

But, the TexRoman font, the lack of lockstep scrolling, and the non-compartmental MathJax rendering causing the entire document to flick-around when making any edits makes this non-feasible for documents > 1 page. I'm also a sucker that needs inline sequence diagrams for my documents.

For now, for me, hackmd.io is king... but, maybe that will change.

Not as fleshed out as, but does support diagrams using plain text http://ivanceras.github.io/spongedown-editor/

Thanks! I don't know which browser/os you use, but for me hackmd.io is a lot more flickering / slow to render (maybe it's different on other browsers than the ones I use).
