I've only driven the 6 speed and have read about the E gear and for me I'll stay with what I know the the 6 speed is driver skill if you can handle the driving the clutch will last you. The E-gear have some historical and inherant issues that you may want to be aware of It's a comuter driven clutch that provides free wheel and drag according to wheel speed, brake position and engine RPM. So in stop and go traffic the tend to heat and wear more than a good driver might in the same conditiion and in reverse the clutch packs never fully engage so they constantly slip so plan your car placement. Trying to back up a hill may be a costly endevor and severly shorten the life of the clutch. And as you may have guessed the E-Gear is more costly to replace. But I'm a traditionalist and I like the 6 speed

I hope this was helpful and what ever you get Enjoy the ride
