all the below, is of course, my opinion:
not counting pure shows, fireworks and other spectaculars, meet and greets, etc.
i tried to compare very similar ride types, like rsr versus test track.
Pure Dark rides technically are all very similar, but I didnt try to compare those, unless both parks had the same dark ride like Peter Pan, or winnie the Pooh, or little mermaid.
as well, it’s hard to directly compare coasters, and there are no identical Coasters at both parks, except big thunder and space mountain , so they are listed that way.
attractions at WDW that DLR doesn’t have equivalent:
enchanted tales with Belle (this is more of a meet and greet/show though)
