Tell me what you think is the best anti-depresant drug available?

I've tried numerous medications and had given up on meds for years. I too hated the side effects. Unfortionatly my depression didn't give up on me. After my fourth visit to the psych ward I was transfered to a different hospital (I wasn't happy about ir at the time)which turned out to be the best thing for me. The doc's there convinced me to try meds again. They tried me on Welbutrin. It was a vast improvement.
