Really depends on what your app does/what field it is in (what do other apps in the space do?), and there are nearly always going to be users for which one of the two is not an acceptable solution.

For social type stuff, Facebook/Twitter seems quite established, with professional or technical tools I'd be more careful.

yes, you are right. I am thinking of adding my own implementation. Thanks for your input, it was useful.
