FWIW, in terms of era comparisons it's worth noting that while the early 1990s league was strong, the 1996-1999 league was not. Not only was there significant expansion, but there was a big talent drought. The late 80s/early 90s drafts were mostly poor. While the he 84/85 drafts produced Olajuwon, Jordan, Barkley, Stockton, Malone, Ewing, and Mullin, the 1986-1991 stretch produced only Robinson, Miller, Pippen, Payton, Rodman, Mitch Richmond, and Mutombo. There were a lot of would-be stars who, due to injuries or otherwise, never lived up to their potentials -- Larry Johnson, Derrick Coleman, Danny Manning, Pervis Ellison, Danny Ferry, Len Bias, and Chris Washburn were all drafted in the top 3 from 86-91. As a result, the 84/85 classes ended up dominating the league long past their natural primes.
In the 1998 Finals, Jordan, Malone, Stockton, Rodman, Hornacek, and Harper were all 34 or older, and Pippen was 32. I would bet a lot that we'll never see 6 out of 10 starters aged 34 or older in the Finals game again. Jordan won the 98 MVP at 34, Malone won the 99 MVP at 35 -- we probably won't see someone that old win the MVP again either. That a bunch of old guys were still the best players in the league shows how watered down it was.
The league didn't recover until the 96/97/98 drafts added Kobe, Iverson, Allen, Nash, Duncan, McGrady, Nowitzki, and Pierce, who along with Shaq (92), Kidd (94), and Garnett (95) would collectively dominate the league for 10-15 years until the 2003 class ascended, as the 99/00/01/02 drafts were even more dreadful than 86-91.
