Cambiocorsa vs SMG vs Tiptronic

seeing that there is considerable about the clutch system on our vehicles in regards to life, adjustment, launching issues, etc etc, ...do any of you have experiences with the other systems? If so, are they plagued with the same isssues? Are they worse/better performance wise?

I have driven my buddys Porsche with Tiptronic and to me it was a very smooth system. He has never informed me of any issues.

I understand Lexus is using paddle shifting in their newer IS series vehicles.
