Yeah, I think costs spiralling out of control and low-capacity attractions were certainly a characteristic of the Iger years. Cheapness, though, wasn't. If anything, he seemed to open the spigot of cash and it was what WDI did with it that was often underwhelming. That is, of course, something he needs to take some responsibility for as CEO.
I find it harder to lay single projects like BOG that were perhaps poorly executed at his feet. The concept was good and I'm sure it had a healthy budget, but the execution was... not great. That, to me, is very different from something like DCA or WDSP in which the CEO clearly had to have signed off on a major project designed and planned to be a budget version of a Disney theme park with the theming stripped down to a minimum.
Isn't River Country closing a little like Discovery Island closing, though? Did WDW really need the older and hokier water park after Typhoon Lagoon and Blizzard Beach opened any more than it needed Discovery Island after Animal Kingdom opened? EDIT: I see someone has pointed out Eisner closed River Country anyway!
As for the subs, they did close at Disneyland under Eisner's watch with no replacement until the Iger years. Thankfully they hadn't already filled them in over there. Stuff like the Keel Boats and canoes at MK also disappeared, and I think it was under Eisner that the upper level of JII became dead space. In other words, I'm not sure it's quite so clearcut that one liked to close attractions with no replacement while the other didn't do that at all.
Worse is subjective. I don't like them and haven't seen most of them, but you again can't say they don't at least try and bring in top talent and give the live action remakes a healthy budget. Things like Bambi II were barely above tv animation quality.
And Heimlich's Chew Chew Train is far more cheap-looking than Rise of the Resistance
I don't quite get this general way of comparing the two by arguing that the bad things Eisner did that Iger didn't do he would have done if someone hadn't of stopped him from doing it or if Eisner hadn't of done it first.
