Oh boy! ANOTHER suspension mount thread. I'll save us all some time:
1. They DO enhance resonance at low tunings, but some people either don't hear/want the extra resonance or tune their drums so high that the effect is negligible. Also, in order for it to have its full effect, you need to take off the original mounting hardware.
2. They make something vintage look newer, which takes away a slight bit of mojo, true, but the result is sturdier mounting in the case of otherwise "I wonder when is this old hardware going to fail me?" situations. Some people like the streamline look and the dependability, whereas some people desire the look of the original hardware or are just set in their ways.
Neither side of the arguments are correct or incorrect. Everyone's opinion is recognized as valued and important, but just as much as everyone ELSE'S opinions. Let's keep this civil, gentlemen...
