Speaking just about the lands, and not the actual rides...
People will probably say Star Wars is really big but feels like much of it is soulless -or- considering its size there wasn't much to do.
People will say Nintendo is small and cramped but damn there's a lot going on.
Both lands will offer multiple rides, restaurants, and character interactions but Star Wars has the luxury of size while Nintendo will have more rides (to start.)
One of my fears is, like Pandora, the look and feel of Galaxy's Edge will not resonate with fans as much as being on a planet or location we know from the original trilogy. Even if they feature Batuu in a later film, it's not going to connect the way being on an Star Destroyer for the Battle ride or flying the Falcon will. The rides will be stellar, but the land may as well be Morocco at Epcot, beautiful and immersive, but not nostalgic...
Not nostalgic the way walking through the Mushroom Kingdom will be.
