Honestly, I liked both about the same. The Eisenmann gave off a little more cabin rumble. I didn't realize any gains with either, they do make you get on it a little more just to enjoy the note. The Eisenmann has a really nice aggressive note, the AA is smoother and has a higher pitch. I thought the Eisenmann gave off more interesting noises/blips during shifts.
