1. Over 66 years of league history, only 3 teams won 22+ games. Meanwhile, there have been 66 titles awarded (funny enough, 22 times more titles than 22+ games winning streaks).
2. The achievement in itself is more historic. I am a big fan of the NBA and read a lot about it, but even I (perhaps because I only started watching in the '90s) can't tell you who won the title in '75 or '83, but I knew who had the 2 best winning streaks in history, as well as who had the most wins in a season (even before the Bulls broke the record and then tied the former record).
3. Part of the reason titles are valued over winning streaks is because winning streaks in themselves are not an official goal and are not rewarded and recognized as such. But maybe there should be some sort of an award for team and personal excellence.
4. Part of the reason might be that the NBA is treated almost as an individual sport by many fans and media, while this is a team achievement. Just like the title should be, instead of the narrative of one superhero battling out by himself, sometimes against his nemesis (Bird and Magic), sometimes against the history books (Jordan), sometimes against the entire basketball world that just wants to see him fail (Lebron).
Such superhero-movie-like narrative might sell better (after all, superhero movies sell incredibly well, or they'd just stop making them), but it really diminishes everyone else's contributions. Even if one guy is head and shoulders above his teammates, NOBODY won alone. NOBODY.
PS: Yeah, I'd choose the title as well. Because if somehow the Heat manage a 4peat, that would be better than what the best teams in the modern era achieved. Including Jordan's Bulls, a team that I loved - but I love seeing records broken as well.
