SimpleNote works very reliably for me (including sync across devices) and always loads quickly, including on mobile devices. I find the most important thing for note taking is just the ability to quickly get stuff out of my head and browser tabs, including only when mobile is available. SimpleNote is missing organizational features (just has tags), but their search works well and it seems enough for personal use. Most of the new note taking apps are tackling organizational knowledge sharing and are bloated (slow and resource intensive) for the personal use case. I do use coda.io for organizing knowledge with tabular data.
