90's definitely. I don't know what I would have done without Britney. I'd say 70's were a cool era where sex and drugs was popular, but they all grew up to be the thing they hated the most so I'd rather choose the 90's than back then.
Right now. Imagine life without the internet + the technology we have right now, and back when Racism/Homophobia etc was at an all time high? At least now we have some level of progression.
