I played on 2 steel RC snares and both sounded amazing.For me, the sound. Then the built quality. After that comes the look - unless the snare is incredibly hideous.
I just played e.g. the new Recording Custom Aluminium snare. A hell of a snare, really really great, no, awesome(!) sounding. It's not terribly pretty, the snare strainer is also a bit uncomfy for me but the sound of it really makes me want to buy one.
The maple hybrid 14x6 I also played would also make a great all-rounder, never thought I'd say that about a wood snare but that was just ignorance on my part.
I was waiting for a fairly-priced brass snare, so I can't wait to try one out for myself.
