I just took delivery of my 328i 6MT last Thursday and the gearbox is slicker than a cat's ass. No notchiness in any of the gears and the clutch is smooth as butter. The only "tricky" shift is the 1-2 which is still relatively easy compared to my last manual car (G37). Plus, my 328 has the Getrag trans whereas the 335 has the ZF, which is a better transmission. So no issues with F30 manuals.
