When I bought a Z4 I was going to get the SMG gearbox but was worried I would miss the 6mt. Then the 135i had the DCT. That is a much better gearbox but I still had doubts so I went with the 6 mt. This is my 3 rd BMW with the 6 mt and I love that gearbox. I can shift with WOT at 6500 RPM and not hit redline.
