Yeah, Twista is indeed faster than Tech... But again, when it comes to clarity and delivery, Tech is the coldest, but not the fastest. Droop is ill with it especially on Under Pressure, I believe that is the name, but he stumbles the whole time and falls off... Not too attractive to the listeners ear. My rankings would be... Out of the 3 mentioned...
1. Tech (clarity and ill use of words) More appealing.
2. Twista (the ability to rip it as fast as he does)
3. Droop (Raps too fast for his own good, slow it down sometimes)
