That's easy.
If MPG / fuel costs is no issue: 550i all the way!
I don't know about SA but throughout europe the 550i is so expensive that an M5 should be considered as well.
On the other hand, I own a 535d and an e92 M3. And in daily drive conditions there's no big difference in performance between the two. The diesel is pretty impressive.
