Do you know the A.A. to be higher pitched than Eiseman? It's hard to tell from some of the audio clips (basic audio equipment and my crap speakers).

pros- nice higher pitched tone, almost zero drone, bolt on no cutting, dyno's to prove the gains, adjustable tips.

cons- expensive, for me a little quiet (can solve with a cat delete but more $), some people say the NCC from behind looks weird

Eisenmann (assuming race)

Pros- Great deep grumble and deep tone, unique sound, nice tips, looks similar to stock but not as bulky underneeth.

Cons- very expensive for just a muffler, slightly more drone then AA, non-adjustable tips, not bolt (YET!) until the pipes are out, not much weight reduction compared to stock, no dyno gains for just the muffler itself

Both are great exhausts just really depends what sound you want and how loud?
