I did, just recently; the biggest difference, to me, is that you have to configure synchronisation of PDFs yourself, if you don't want to use the Zotero web account thing to do it for you. I haven't tried the Zotero account file-syncing option, myself; I just use the Zotfile extension to make it copy the files to a Dropbox folder. ETA: The firefox integration of Zotero is great, and something I missed from Mendeley. Also, I should say, before I switched to Zotero, I was a Mendeley user for about nine years, and did my PhD dissertation's bibliography using it. I'm quite confident Zotero would have been just as good.
