The sounds in here are really good. and it is so easy to use. Its definitely a different way to make drums but its so intuitive and makes better patterns and grooves than I could come up with trying to do it other ways. The exporting is amazing! so may options.
If you dont have your own drum samples (is that even possible), then this is probably mostly what you need. With this gone are the days of hunting for the newest drum packs and loops. Just use this.
