I think it depends on what you're going for. If you're looking for Disney, nope. They aren't Disney. If you're looking for Universal then, again, nope..
For what they do, they do OK. They're FAR better off than where they were 15 years back when they were stuck in debt and selling stuff off to try to stay afloat while at the same time their parks were trashy and the employees horrible. They've really come a long way. The parks are a lot nicer, the employees are friendly/helpful. No, it's not Disney. I don't know that they're much more than a regional destination but I don't think you could say that they're still run horribly. 10-15 years ago, absolutely. Now? No. They actually seem to be doing OK now.
I think they're still recovering from the idiot decisions from the late 1990s, early 2000s, though, with that bad perception being stuck in folk's minds.
I think that you could make a pretty good argument that Disney parks are being run into the ground right now with too-little, too-late on the updates, festivals instead of updates, increased costs and lots of cutbacks in staff, attractions, and entertainment.
They're still packed right now because people make plans and don't know but when you see trash cans regularly over filling and general poor upkeep of the parks and you're paying a premium, you're probably going to remember that sting in years to come.
