Question: Who is the best rapper of all time?
Position‹8 of 8: Tupac Shakur is the best rapper
Argument: Tupac created an incredible amount of material in his short career.

Tupac was tragically murdered in 1996, but he had already left his mark on the hip hop world by then. The quantity and quality of music that Tupac created in his 6 short years as a rapper is nothing less than extraordinary.

The argument

Tupac died in 1996 at age 25, just 6 years after he began his rap career in 1989. Given this incredibly small time frame, it's impressive that the artist was able to produce 11 albums and 2 live albums. Even in his songs, Tupac was extremely efficient without sacrificing quality. The track "Hail Mary" was recorded in just 30 minutes with only a couple of takes. Tupac is the greatest because of what he was able to accomplish in such a short amount of time.

Premises

[P1]The best rapper should be judged by how much quality material they produce relative to their time in the industry. [P2] Tupac released 11 studio albums and 2 live albums in only 6 years before his death at 25, recording standout tracks like "Hail Mary" in a single 30-minute session. [C] Therefore, Tupac is the greatest rapper of all time because of his extraordinary productivity and efficiency in such a short career.

Counter-arguments

Tupac was an incredible rapper, however, efficiency does not make him the best rapper of all time. Efficiency was Tupac's major flaw. Masterpieces take time to create, and unfortunately Tupac didn't create with patience. Had he slowed down and created less, his music most likely would have been the greatest of all time.

Rejecting the premises

[Rejecting P1] The counter rejects the criterion outright: volume relative to time in the industry is not what settles who is best, and on this reading the efficiency the premise celebrates was itself the weakness in the work. [Rejecting P2] The same facts are read against the conclusion — recording at that pace, including a track completed in a single half-hour session, is taken to show work made without the patience masterpieces require, with the counter arguing that a slower and smaller output would have stood higher.
