Mercedes E63 AMG W212 6.2 or 5.5?

I've decided that I need an AMG in my life, but can't decide on the n/a 6.2 or newer 5.5tt. I feel that I should get the n/a and enjoy that brute of am engine.
Has anyone driven both? If yes, what are you thoughts? Is the n/a more reliable?
Thanks in advance

Thank you for your response. Bummer about the gearbox, is it really that bad? In what is it bad, dumb witted?

Food for thought on which one to get. I love the idea of the big n/a, and its Jekyll and Hyde personality.
Best thing is to try both and see really...
