I have an IMDN Pro now and hopefully adding a JP Premium shortly. For me my wife struggles with Iron Maiden as ball times can be extremely fast if you don’t hit your shots right. Also the outlanes are brutal, but I love the pin and is always my first go to in my small lineup. Definitely has that one more game feel and hitting the loop with the upper right flipper multiple times is a rush. Don’t think you’d go wrong with either pin though as their both rated very high and have great game play. I’ve played JP a number of times and really enjoyed it. Different layout and a lot of depth to it.
