Since Pacquiao obliterated Cotto, he's only had one exciting fight in a 4 year stretch and that was the 4th Marquez fight. The other fights he's had have been either underwhelming (Bradley fights) or just too lop-sided (Rios, Clottey and Mosley) without finishing the opponents.
IMO GGG is far more exciting. You wonder what he's going to do next and how he'll finish his opponents. He just knocked out one of the best fighters in his weight class while off balance. The power is what makes him so intriguing to watch.
