Cons
Con Custom grammar and spell checker
It does not work well in French (and probably other languages).
Con Not as beautiful as StackEdit
Con Cannot organize notes
Doesn't have the ability to organize notes or create notebooks.
Con Slow servers / problem with online / offline switching
Servers can be slow / down for a few seconds preventing from working on the documents currently being edited.
Con No PDF export support
Con Tries to be smart
It guesses what you want to do and tries to help, often in a wrong and annoying way, for example it when working with list items. Ironically Markdown was built to solve those problems (you format yourself with simple codes and it just works).
Con Some of the features are not consistent
Con Must use third-party service for sync-ing (Dropbox, etc.)
Boostnote does not have sync-ing capabilities and relies on third-party services to fulfil notes storage. There are additional steps involved to set this up.
Con Can't work in "real" offline mode
Con Very poor syncing
Data loss may occur on syncing.
