Sorry my friend but there's no correct answer. Any one of the mics listed would sound best on a particular singer in a particular song context. Sometimes a 57 is best, sometimes a U-87.
That being said, the 4050 wouldn't suck I'm sure. I've used 4033's with great success. I've no experience with the other two.
"Warmness" is a subjective quality. There's no way you can rate "warmness" : it depends on how and on whom the mic is being used, as well as who's listening...
Signal to noise ratio isn't something you should be concerned with when choosing a mic since all the ones you mentionned have very low self noise.
Same goes for longetivity, all these mics should last a lifetime, if taken care of properly.
Sorry, looks like you're gonna have to try these mics out yourself
What is your budget? Personally, I would go for a used mic. Soundelux is the line of mics that I normally recommend, simply because they are fantastic for a fair price.
