Here’s my take, I like to use:
SPRINGPAD for simple general notes that I plan on sharing with others (usually not work related).
EVERNOTE for serious note taking for myself(often for work).
GOOGLEDRIVE/DOCS for specific office documents I want to save and sometimes to share (work and play).
DROPBOX for using custom portable software and their related files. I really like the old application Keynote to organize scripts and coding.
