I dropped and then signed up again because I needed some way to sync my 1Password data from my laptop to my Android phone (I was previously using iCloud on an iPhone). Annoying, but I sleep fine at night.
I use WiFi sync on 1Password specifically to avoid syncing through Dropbox or iCloud.
Anything stored on servers in the USA, UK, New Zealand or Australia should be treated as compromised, exposed or public information.
I certainly wouldn't hand my 1password file to random strangers in the street, much less anyone associated with any kind of law enforcement or intelligence agency.
So treat cloud storage as that random stranger in the street. Sure, E's always there with your bag of loot and E's pretty reliable about giving your stuff back, but you have no guarantee that E isn't letting everyone else look at what's in your bag (or that other folks haven't figured out a way to see what's going into and out of the bag, or figured out a way to determine what's in the bag without letting E know they're looking).
