I have Eisenmann Race exhaust on one of my BMWs and I have closely examined and heard Dinan and Akrapovic on few occasions. Akrapovic just stands out in comparison to others.

If you look at construction of three, Akrapovic is the most detailed and intricate, with better material(Titanium), workmanship and quality. Dinan is the cheapest looking of three.

Akrapovic is the lightest of three. Dinan for some reason does not state the weight of their exhaust, but is unofficially known to be heaviest.
Akrapovic is biggest setup(see pics below) and they also proivides the detailed information about their exhaust.

See pics and videos of 3 below.

You can get better than list prices on Eisenmann and Akrapovic.
Best comparison is seeing and hearing the three in person. I am getting Akrapovic next time.

BMW also uses Akrapovic on their Safety cars...see videos below.
