If you are mostly using EBSCO databases and web sources, downloading lots of PDF copies of articles, want to work offline, want to use your citation manager on an iPhone or iPad, use Linux or Open Office, and/or want to collaborate with colleagues outside of the university, try Mendeley.
If you use a variety of library databases (not just EBSCO), are nearly always online, use a non-iOS smart phone or tablet, and/or want the convenience of having everything online, try EndNote Web.
Don't worry if you change your mind. Both systems can export your citations and import the exported files from another system.
