Definitely what OP meant.

To counter point, "rappity raps" with no substance are just as mediocre as lazy, non-technical wack rappers.

Making enjoyable, well structured songs and entertaining hooks are essential parts of the song structure lost on "rappity rappers" but a strength of the lazy, non-technical wack rappers. Which is more important? Depends on the listener.

Personally, I believe the greats combine the ability to be lyrical, witty and creative while still being able to choose quality hooks, pick enjoyable beats, and make great MUSIC (defined as "vocal or instrumental sounds (or both) combined in such a way as to produce beauty of form, harmony, and expression of emotion.")
