You need to do the numbers yourself using the food that you like.
For us the DDP is too much food, is now too expensive for what you get and to be honest with you, causes you to worry more about eating your next meal, than enjoying yourself.
I can eat at home and for the most part, Disney doesn't offer anything special in the way of eating.

This, exactly.
It's ultimately a personal decision and you just have to crunch the numbers, but it is unquestionably based upon what and how you eat, and if doing DDP requires you to eat a different way than you normally eat to realize a cost savings over paying OOP, you're not really saving money.
We did a trip that our relatives organized last June that included DDP. We got a ton of food, but it was frankly way too much food, and I felt like I was constantly planning around dining reservations to make sure that we didn't waste a credit, including eating an enormous plate of pasta at Tutto Italia at 2:45 in the afternoon because, you know, who doesn't want a heavy Italian meal right before heading back out into 95 degree heat?
Went back in January, and decided to go without the dining plan, eat whatever we wanted and see what happened. What happened was that we spent less on food -- significantly less, in fact -- and felt much less constrained from a time standpoint because we weren't always beholden to a dining reservation.
Full disclosure, though, we didn't eat as much as we did on DDP, which was actually a good thing. Probably ate more counter service meals than we did on DDP, but the table service meals we did eat were much better -- mostly Signatures -- and I enjoyed them more because it seemed a bit more special and I was eating there because I wanted to, not because I had to use a TS credit. Also in the interest of disclosure, I'm a bit of a food snob, and generally speaking, I don't think the food at most regular TS places is good enough to warrant the cost or the time, so I'd rather just get something to sustain me and spend that time doing other things.
To each their own, though -- it definitely works well for some people, but for us, we'll likely never do it again. Good luck!
