Justin,
I use both on my "live" gigs. I would recommend 57 based on versatilty. My stand by mic when all else fails is the 57. As for the clip thing, you can use a butterfly arrangement made by Mic Eze. I find it more usable than the 604 clip. You can mount the 57 holder on it. Price for the 57 at GC is about $80 and less than $10 for the MicEze, so price is not a concern.
