Which year(s) or decade(s) would you consider to be NJPW’s “prime?”

Hi everyone! I hope y'all are having a great day. I'm curious to which year or decade would y'all consider to be the “prime” of NJPW? I finally got around to watching it full time but I've seen older matches from the 2000s and some from the 90s. I personally can't choose but I'd have to say the early late 90s or early 2000s. I'd love to hear y'all's opinions as well!
