When I was using Epson papers, Premium Semigloss Photo Paper was my favorite. Moved away from it mainly because of "gloss differential" or "bronzing" issues (use the terminology of your choice!).
I'm now using a mix of Breathing Color media and Ilford media. The only Epson media I'm using (or recommending to my clients) is Epson Standard Proofing Paper (240) for, obviously, press proofing applications.
