Citation managers are a central place for you to gather and organize references for a research paper. Citation managers can save you time by creating automatic references and in-text citations. Automatic citations frequently have errors, so you must check their accuracy before submitting a research paper.
This depends on which one you like more.

EndNote Basic has the 21 most-used citation styles but cannot create unique citation styles, which are often required by journals. However, its "Cite While You Write" tool for automatic in-text citations in Microsoft Word tends to be less glitchy than RefWorks.
