A little late to the party but here are my thoughts:
-We do the DxDP because we like 3 table service meals a day. When we have gone without the plan and did only CS, we preferred the unique items as well. CS in Epcot is better than any generic CS at Six Flags, etc.
-We just went on an all inclusive trip at an expensive resort in Mexico. I spent the whole time thinking about what I will eat at WDW in May because I couldn't eat much there.
-I have severe food allergies. WDW is the place where I can eat with as close to reckless abandon

as I will ever be able to. So when I am there, I am not spending my time eating burgers and fries or ordering Papa John's (which is not *my* choice for pizza at home). I'm going to eat everything I want to try but usually don't because I typically have to worry about the ingredients. While in Mexico, I didn't have a chef at each meal planning out the meal with me. For all this attention to detail, I gladly pay the fees for DxDP and will do it everytime. Heck, my oldest child and DH are spoiled with the fact that mommy can eat everything at WDW. They make sure it is on the plan for each trip.
-While the prices are expensive compared to a lot of fast food places, Chik-Fil-A is more expensive than McD's. A meal there typically costs me $5.50-6.00. So the difference in cost isn't that great for the convenience of staying in the parks.
-The OP has just learned that there are reviews on this site and others but is a member since 2006

To each their own. I have used this site as a resource. I wouldn't step into Electric Umbrella or the ABC. I've read too many reviews just on the restaurant board that say thumbs down

With good planning ahead of time, you can make a cheat sheet of the places with positive and negative reviews.
And for what it's worth: I like Nathan's hot dogs the best
