The Rode NT2A is a superb condenser mic and way better than it should be for the price. It is very neutral, has low noise, and offers three choices for attentuation (0, -5,-10). I use this for vocals in almost all situations, and it is good for acoustic instruments.
The U87 is the standard by which we judge vocal condensers, but it is a $3,500-4,000 mic and I am not sure you would be much happier than if you spent $400 (or less) on the Rode. Plus, if some idiot breaks your Rode, you can buy another one. If he breaks your U87, you will have to kill him.
I use an ElectroVoice RE-20 for narration, high pressure sounds (like close mic'ed guitar amps), and some singers (e.g., basses in quartets).
If you want to mic drums, we will have to write a book to cover the choices and I don't do this as much as I used to. (It is a pain.) The short answer for those who can't spend a fortune is to put an AKG D112 on the kick, Shure 57s on snare, tom, and maybe use the Audio-Technica ATM450 (or the twice-as-expensive AKG C 451) for hi-hat and overheads.
If you buy a D112 for kick, you might experiment with it on vocals to see what you think. I would not use it normally but the peak it has somewhere around 3-4K can give you a cool sound on some people.
