Before I get flamed, I have tried the "search" and not found an answer.

Having thought about an RS6 at one time and being put off by the gearbox issue.....how reliable are the auto gearboxes in the B6 S4?.....also, are they all tip-tronic?
I know there is not as much power being put through the box so wondered if they were fine in the S4.
Without wishing to start any arguments between manual and auto owners, which is the better option?
Many thanks in advance
