Yes, I went with the M Performance. I didn't have a chance to compare the M Performance with an Eisenmann in person, just went off of clips and comments/reviews. Here's a great review for a guy that has had both. I totally echo his comments on the M Performance. The M Performance is a very linear sounding exhaust in respect to throttle input.
