I do not like the NTK on most vocals, actually. It's good on other things, but for vocals I find it too essy and thin. I liked my Baby Bottle on vocals before I had to sell it. I liked my ADK TC on vocals before I had to sell it. (BTW, I sold both of these mics to get a Soundelux U195, which is...
Another vote for "won't knock your socks off, but rarely stinks." It's pretty good on 85 percent of sources, but not really amazing on anything, in my experience.
SM57 is better/more versatile in the studio, IMO. The SM58 is a very good vocal mic for live use, though.
Many people contend that if you take the ball off of an SM58 it is essentially an SM57 though. It may be worthwhile to get the SM58 and get both flavors (assuming that these people are right.)

But no matter what, you can get a wider dynamic range by not using a compressor and turning down the input level. I'm not saying that's the best strategy (I usually compress on the way in for guitar amp, drums, and vocals), just that a device whose purpose in life is to limit dynamic range...
There's a reason why you have negative rep. Not that there's anything wrong with the C1 but that you consider it so obviously better than the rest of those mics. Those are all fine mics, with the possible exception of the Samson.
