I am new to the forums and Bookends so please go easy on me

I have been trying out Bookends and Papers and have been trying to make comparisons between the two and also if it warrants purchasing both programs. I have come to the conclusion that like another poster has said, Papers is "prettier" to look at, but Bookends seems to be a superior. program. I can't seem to see anything obvious that Papers does extra or more efficiently that Bookends doesn't. Papers doesn't appear to let the user have the database in Dropbox where Bookends does. I have even tried with Papers having the database on a usb stick (like I do with Bookends), but that keeps coming up with errors. Both programs do "matching," and attaching files. In addition unless I have my stupid head on, Papers only seems to export in-text citations successfully to Bookends and not the full reference.
If there is anything obvious between the two programs I have missed that warrants buying the two programs please tell me. Or if this topic has been posted before, please direct me to the correct thread.
