FWIW I prefer Zotero because I find downloading the pdf to actually be rather annoying. I just save the citation and double click on it to open the article in my browser whenever I need it. No metadata extraction necessary b/c Zotero pulls metadata from a doi or PMID (which is a quick copy and paste from the web) and unsurprisingly does it much better than Mendely pulls metadata from pdfs.
