Every factory snare these days, that hasn't been re-edged by hand, produces unwanted overtones. Not sustain (that you might want), but a nasty sharp after effect, no matter how you tune it. I'm a big big Aquarian fan, but in some cases, especially with snare drums, I go Evans.
Pros:
They typically have a dryer sound, perfect for post punk/prog rock/metal, or even drum & bass. The "Edge Control" does exactly what it says. The reverse dot shortens the decay even more, and also adds to the life of the head. It can be tuned quite low as well. I'm using one currently on a 10" x 5.5" Mapex Walnut Shell.
Cons: None for me, but others might complain that it's too quick.
Final thoughts: Prince would have loved this snare head.
