i saw KRS perform live a few years ago, he was dope as fukk, just as good as i would ever imagine. lots of rappers have gotten technically better over the years, Tech N9ne has always been getting better as far as flows go, Pharoahe Monch, Sean Price, Ghostface, as elementary as his style is Ice-T is still dope when he spits as shown by his little freestyles on Combat Jack a few weeks ago, he was spitting shyt he wrote from the 70s & it was some of the most gangbangin-est shyt you'll ever hear and the flow was ill. dude is in his 50s i think.
