Yamaha is by far the leader in useable fills, intros and endings. I use the simple endings 90% of the time (OF COURSE YOU HAVE TO MANUALLY SELECT IT EACH TIME ON THE 2000).
I rarely use intros, preferring to play them myself to suit the song. I do use the count-in intros a lot for breaks during the song, again having to manually select them from the screen each time you change styles (I didn't shout that time, because Yamaha isn't listening anyway).
