I've POTC plenty of time, and it is a machine I just don't like. That massive transparent shroud in front of the ship and the ball draining horseshoe on the RHS - Just really poor design. I loved the movies BTW - it is the pin that is poor.
WoF is just a really nice flowing machine. It has outlanes that remind me of a 60's EM title that escapes me at the moment. The theme is crap, but the game is really nice and "family" friendly as well.
I guess the thing about pinball is that there is a variety of pins and a variety of people; I just really enjoyed POTC - didn't notice the horseshoe ball draining at all.
I will keep in mind what you have said re WoF as I imagine they would be a bit cheaper than some of the other later pins.
