Personal experience: I made the switch soon after starting my PhD and never looked back. Also, their Connector plugin for Firefox is a life saver. 90% of the time I only have to lookup the title of a paper on DBLP, then export it as BibTeX and pronto, the reference is now in my library with most of the relevant metadata. Much better than Mendeley's quite opinionated plugin (which also won't work unless you log into Elsevier's servers)

I never used the Mendeley plugin, but I imagine it must be pretty horrible to store PDFs from all the convoluted sources and proxy setups or library file-servers that universities use. It probably only works well if you logged into your Elsevier(tm) account.

In any case, the Zotero plugin works great and just saves Metadata and PDFs, as it should. For the usual preprint or paper providers, it works perfectly.

So even here, using Mendeley is just bad.
