whats a good pick for a mic for hip hop and rnb? u87 or tlm103. should i get the Neve 1073 or 1176 universal audio?

I was wondering how much of an upgrade the Shure SM7 is over the SM-57/SM58?

I'm also looking at the Electro-Voice RE-20 and the Sennheiser MD 421.

Any help would be appreciated. Right now I use a Audio-Technica AT-3035...which I like. However, I want a good dynamic so I have some variety.

Hi, I have an AKG C414 and I was considering selling it to buy a Neumann U87. I record Hip Hop and Mostly RnB and I use my Mics with an Avalon 737 sp.
1. would you recommend the U87 for RnB vocals or is there a better mic for this purpose in the same price range.
