One resort has teetered on the edge of the financial abyss for much of its two plus decades and has been hamstrung with debt. The other is a virtual ATM for its parent corp. I would expect WDW to be in far better shape, far better run than DLP. In some ways it is, in others it is not.
I know Paris has quite a few excuses for the state it is/was in, but in my personal opinion, DLP circa 2013 was the worst castle park I've ever stepped into. I'm sure it was similar, if not worse than your 2012 experience. It was an embarrassment. That was the peak of the true, 'we are going out of business: "ghetto kingdom" '. With a friend who was a Disney parks virgin in tow, I kept wishing we had gone to any other resort, yes including Magic Kingdom.
I think you are a little too kind on DLP based on both nostalgia for what it was, and forward looking to what it will be again come 2017 or late in the decade.
Sure it's all pretty (well what isn't falling apart), it's all plussed, but the attractions were/are falling apart and in some cases unrideable (I'm looking at you Space Mountain).
Fortunately, based on the extensive, extensive list of refurbs coming it is all looking on the up and up. But I cannot be convinced Magic Kingdom is significantly
worse. Unless the only metric is how pretty the shell looks, but based on New Fantasyland's reception I don't think that earns a park very high marks.
Of course, maybe DLP is just so pretty compared to the ugliest Disney park, in the world, next door.
I think I just had a disappointing experience and was let down by some of the praise DLP often receives on these boards.

My personal list is DL -> TDL -> HKDL -> MK -> DLP. From what we sort of know in the future, there is actually a chance TDL could briefly overtake DL and certainly DLP has nowhere to go but up.
