We now have both an E53 and an E70 in the stable. We are still learning the ropes with the technology rich environment of the E70 chassis. The newer vehicle, as other have stated elsewhere, is much more refined. It reminds me of stepping from a 02 chassis to a E12 back 35 to 40 years ago.
Do they have problems? Of course, but every vehicle out there has plenty to complain about. That's why there is some sort of vehicle repair station on every street.
When you accept the possible problems and make plans for remedial maintenance you end up with a splendid personal chariot.
