Not all tube mics sound the same. Neither do all hop hop vocals. There is no good answer to this question because every situation is different. Generally, you don't pick a mic based on how it was designed, you pick it based on how it interacts with whatever you are putting it in front of. There might be a hip hop vocalist whose voice and delivery woyld be perfectly suited by a specific tube mic, but if you are going to be doing several vocalist with only one mic, it would be safer to get a higher quality solid state mic. Solid state mics are cheaper to make, so you will get a better one for the same money that you would spend on a tube mic.
