So after all of this, all you wanted to say was that O'Neal and Hakeem were better scorers? O'Neal? Sure, why not? Hakeem not so much. But why did you say that he wasn't in the same level of dominance as those two? Do you understand dominance and scoring are two different things?
Per 100 possessions, which actually does take into account pace, Duncan averaged 30.1pp100, while Hakeem had 30.3pp100. Duncan had a peak of 33.5 and Hakeem 35.8. not really that big of a difference. But if you factor in assists, Duncan averaged 4.7ap100, and Hakeem had 3.4ap100. Duncan's peak was 5.7, while Hakeem's peak was 4.7 (same as Duncan's average).
O"Neal was his most dominant during the three peat. The Lakers scored 100.8, 100.6 and 101.3 ppg.
Duncan was most dominant from 2001 to 2004, in those years, the Spurs averaged 96.2, 96.7, 95.8 and 91.5 ppg. That alone accounted for 5 to 10% of the difference. And the 120 ppg was an illustration to explain to you what pace means, since you either do not understand what it means, or is actively trying to avoid the topic.
And no, Shaq had the lowest average in his prime in a series vs. the Spurs, averaging 21.4ppg in 2002. In the same series, Duncan averaged 29. In the next year, Shaq averaged 25.3ppg in the series vs. the Spurs, while Duncan aveaged 28. Even in the peak of his prime, in 2001, Shaq "only" averaged 27 ppg vs. the Spurs, while Duncan averaged 23. In 1999, Duncan averaged 29 while Shaq managed 23.8ppg in the same series. In 2004, Shaq averaged 22.5 while Duncan averaged 20.7. To summarize for you, Duncan out scored Shaq 3 out of 5 times in h2h series between 1999 and 2004. Fact check your garbage before you spew it out.
