Azza is not a great maker of cases. Lian Li, on the other hand, is a great maker of cases.
- Edit - Deleted some stuff because I clearly am not super familiar with Azza cases other than to know they aren't very popular.
The Antec 900, the Cooler Master HAF 932 and HAF X, and the Corsair Carbide and Graphite 600s are all very popular high end cases. NZXT makes a lot of really good cases too.
I would stick with Antec, Cooler Master, Corsair, NZXT, or Lian Li, though, if I were you.
Other makers may have good ones here and there, but those tend to be the most popular and for good reason.
