Have a JP2 Pre and JJP POTC LE and really like them both but for different reasons. Shots on both are varied and layouts are a blast. POTC is a multiball bonanza which might be good or bad depending on what you are looking for, I love it. JP2 has the "quest" progression on the playfield a la Roadshow and I like that I don't need to look up at the screen to see my path to the visitors center. Great use of third flipper on both.
Both are staying for a while, I think POTC will be here longer mainly because of rarity (not sure I could ever afford it again if I sold it). POTC might be my favorite game but JP2 is right there with it.
