I think that's debatable. USF has certainly seen dramatic change over the last decade, but I don't think it's been particularly for the better. And not because individual attractions aren't good, but because so many of them are so similar, either to each other or to better rides in IOA.
For me, USF still needs a lot of work to get it up to IOA's level. Nintendo would have dramatically helped in one fell swoop, but that's apparently off the table now.
