Likin' the 2003
I graduated from the SM58 to the MXL 2003 a couple years ago, based on reviews I'd read. Since then, I've also recorded my vocals through an AKG 414 (I think), and a "thousand-dollar" Neumann. I prefer the sound of the 2003, with the 10dB pad. Using good mic technique, I can belt it out, or get up close and growl. I guess it comes down to what works best for your particular voice. More expensive doesn't always mean it'll do a better job.
