I’d argue with Lion King and an Avatar land it would edge out Disney’s Hollywood Studios. DHS would still have a better entrance street but in terms of attraction line ups I feel WDS would win.
ToT- Both have, although DHS has the better version
Flight Force and Muppets coaster - exact same ride, cancel each other out
Crush’s Coaster and Slinky dog - family coasters, would possible give edge to Crush for indoor scenes.
Runaway Railway and Ratatouille - both family dark rides
Midway Mania and Spiderman - I’d give Spiderman the edge over Midway Mania
Flat rides - WDS would win hands down, all of Toy Story Land plus Flying carpets and Cars and new Tangled and UP rides vs Alien saucers at DHS
Cars Tram tour has no equivalent at DHS
Shows - WDS would win for me, Pixar and Mickey and the Magician are good theme park shows, better than Indy and Beauty and the Beast. Whatever replaces the Frozen show is possibly a wash with DHS singalong. Fantasmic vs new WDS nightime show is hard to judge yet.
Would boil down to will Frozen, Lion King and Avatar surpass Galaxies Edge and Monsters Inc.
