I can't stand to listen to most 90s pop now, and I was a kid during then so I figure I would say it was good b/c when you're a kid you think everything's good.
A lot of the Death Row gangsta rap songs still hold up thanks mainly to the samples they used (Dre was/is a great producer, bam.). Hiphop was at its peak in creativity in the mainstream sector at the time; there are still awesome artists like Psyche Origami (they're doing a band thing now, forgot its name atm), El-P, Panacea, Funky DL, Little Brother, MF Doom etc., but they're underground.
But the music that, to me, does it best is from the jungle/drum and bass scene, and some of the hardcore stuff that predates them. The rapid transformation and weaving those genres did during that time frame was
amazing, and so many of those tracks still hold up (I'd say sound even better) now. New techniques were just flying by and no other genre really came close to embracing technology's impact on sound like those did. Except maybe house and garage.
Could argue it's always been that way, and still is today. Noisa, dBridge, Vega, Amit, Decoder, Goldie, Total Science, Paradox, DJ Dextrous, J Majik...if you know where to look the list gets very big very quickly

. And house producers like Kerri Chandler, Jerry Sylvester, Aaron Carl (who passed away a while ago sadly), Masters At Work...
Plus arguably my favorite genre neurofunk/techstep whatever the fuck you wanna call it, got its start in the late half of the decade. Of course I didn't listen to it then, now I curse myself for not being older. And not living in Europe
