He's not a great rapper, but he does have some witty lines, and is fun to listen to when he features. I've never listened to an entire Wayne album, nor do I care to.
That said, he has his legions of fans. One of my workmates asked me to join him at a Wayne concert. I went to see the milfy Sade instead and thoroughly enjoyed it. The Throne have a concert in town soon. Tempted to go, but I'm already dropping a ton of cash for a UFC event at the same place a few weeks earlier.
