Oooo I would go for the regular leather. Although patent leather looks nice in the store, I always felt like it didn't satisfy me like regular leather does. After a while, the glamour of it fades and you start to miss the thick leather feel.
I prefer the graphite patent & am seriously considering getting one. I have the black leather and haven't used it in forever. I was just saying today that I feel it's kinda boring, it looks too much like a doctor's bag. But anyway that's JMO, good luck with your decision
