If you put a lot of weight on theme and are a huge fan of DP then go for it! If theme is evenly split or you like JP, go JP hands down. I voted JP. I have played both and honestly think JP is one of the best machines to come out in a long, long time. Great theatrics, good music, great flow, plenty to shoot for, and one of the best toys to come out in a long while. Still not as cool as DE's T-Rex but I am biased. Either way you will be doing well. Enjoy!
