Will you be doing any HPDE or autocross? The CS is the only one of those cars I would say is somewhat ready for that kind of work.
The C63 will feel like an updated version of your E92, good blend of luxury and performance with a stout motor. The RS5 is more of a GT car but still very capable and comfortable, plus AWD is a nice bonus for inclement weather. Haven't driven the new M5 but it's a huge car and I suspect it will feel enormous -- maybe that's fine?
