As a year, is 2000 more like 1994 or 2006?

Unquestionably 2006.

Tech-wise, things like cellphones, CGI and the internet were a lot more widespread in the year 2000 compared to 6 years prior. Fashion-wise, low-rise jeans and the bubblier 2000s fashion were already taking over in 2000, a far cry from the earthy and grungy fashion of 1994. And if you look closely some of the more gothic fashion in 2000 seemed to already predict the later ubiquitous emo movement in 2006. Music-wise, 1994 was full-on R&B ballads, eurodance, grunge and west/east coast feud-era rap, while 2000 was dance-R&b, trance, post-grunge and materialistic bling rap. 2006 was practically a continuation of all four.

The only major thing that brings 2000 closer to 1994 would be 9/11 and the ensuing political events not being a thing yet really. But the controversial election of Dubya was already a reality in 2000, just like Trump was in 2016.
