I don't think there is a difference between Dish and Direct for live boxing and golf, though D* does do more extended coverage of a couple of golf's biggies. That latter isn't all that important to me.
My adult son and I are discussing what to do with these increases. We both love the Hoppers we have and we share very little as our viewing choices are quite a bit different. I can save money by making the switch, but would lose my archived content as would he. How much value that has is the main conversation. We both could be very comfortable with either service as we have in the past. We both think the Hopper is very much better than the Genie, but that wouldn't be the sole reason to choose to not switch.
One factor that concerns me is that I got my new sign up with Dish a year ago from a dealer who is a personal friend. I don't know when or if he gets dinged if I cancel at the end of the 1st year, I wouldn't want that to happen.
