They are just more specific and more sensitive, which is not always a good thing. I'd say they have more detail and more granularity due to the capsule design, and the phantom power being present.
But I think the Red Hot Chili Peppers singer actually recorded a whole album worth of vocals with an SM57. So it's all about the sound you want to get.
Everyone wants that radio clear sound, so that's gonna be a condenser, more than likely.
