Nothing technical, just my observations: Deeper snares feel a bit 'slower' and more spongy under the stick even at higher tunings. Shallow snares respond much faster but don't have as much body. I personally find the smaller the drum diameter the deeper I like. 12x5 is probably my favorite all around fits into any playing situation I find myself in size. I recently have been playing a 10x5.5 with great success and just got a 13x6 that feels very different after years of small drums but I'm liking it. I typically like my 13 and 14s to be 3-4" depth and no more.
