I disagree with you. I compared the rappers over the years to show that they got more technical with their writing as time went on and stayed relevant because they evolved with the times. I also think 15-20 years is far back enough. I'm sure I can find plenty of wack rappers from the 90s too to compare to what's popular today. Bar for bar flow for flow I know Durk rap better than MC Hammer and he was the first rapper to go Diamond. Then there's Vanilla Ice and Marky Mark that I can remember about. I'm sure Jack Harlow raps better than them even though I don't listen to them. There's plenty of Mcs that were vets in the early 2000s that were considered lyrical back then that rap today switching flows within versus, using more internal rhyme schemes, and substituting simalies for metaphors.
I tried to match artists experience in the early 2000s with today's examples and songs that had similar content. MBY now has been rapping for about 8 years which is how long TI was with Trap Muzik. Country Grammer and The Box were both Nelly and Roddy Rich debut singles.
The only person that I can think of off the top of my head that was rapping back in the mid 90s then and still does it is Method Man and you can see that he changed his rhyme patterns and metaphors to the way people rap today. Meth on On Brind Da Pain to Meth on Lemon from last year. Meth rhyme patterns, wordplay, and metaphors are on a higher level than what he did one Bring the Pain. Id rather listen to Bring the Pain if I had to choose.
My point to begin with is that it's harder to internally rhyme and use metaphors that have double meaning. So from a technical standpoint the bar has been raised although I don't believe that makes someone a better rapper overall.
