I've used Zotero regularly since 2012 or so. At the time I chose it because it integrated with Firefox, though I recall looking into Mendeley as well. If you use BibTeX or BibLaTeX I'd recommend the following extension: https://github.com/retorquere/zotero-better-bibtex https://github.com/retorquere/zotero-better-bibtex I'm very glad I never even tried Mendeley given the database encryption fiasco. Mendeley put a blog post out saying that preventing importing to Zotero was unintentional, but I don't buy it. https://blog.mendeley.com/2019/01/31/the-importance-of-interoperability/ https://blog.mendeley.com/2019/01/31/the-importance-of-inter... Before the database encryption fiasco, I would recommend Mendeley and Zotero if someone wanted a citation manager, but now I recommend staying away from Mendeley as much as possible. The only major problems I've had with Zotero were related to Firefox's switch to WebExtensions. Now adding a copy of a webpage to a citation is more difficult than before the switch, though probably equally difficult as in Mendeley.
