I went with the 1/2 the price model since I already have a primary DC and also the size of the Ultra was a bit big in my opinion for everyday use. Someone who will use the dive features regularly, it's a cool option I guess. The subscription to the dive app plus the add cost of that model was the turn off for me for now.You can get the same features on the different apple model for 1/2 the price, outside of diving and the bigger battery basically. You pay double to dive with it.
