There are still rappers out there who can rap on the level of dudes from the 90's imo. However they aren't necessarily putting out classic albums.
Reks spits as well as anyone imo. Superb flow, strong content, solid rhyming, maybe the lyrical complexity is lacking though. Thaione Davis is another guy with amazing flow who put out great music, although again maybe his lyrical talent is slightly lacking compared to some of the 90's rap. The problem is these dudes don't get enough attention for whatever reason.
