Ok, in my usual way, I went a little overboard here 
Basically I agree with @gingerSnaps543222’s rankings. I matched up a few more attractions that are similar or at least trying to hit the same note. I excluded Meet & Greets and most diversions (Launch Bay, museums, playgrounds, splahs pads, etc.) but included some of the most significant exhibits and walkthroughs. I excluded Pixar Shorts and other minor films.
First up is Rides - split between all rides at Disneyland with their WDW counterpart:
… and rides only found at WDW:
Next up is Shows:
Here is Vehicles (a loose category but seems distinct from rides). I excluded a couple of negligible ones (Buena Vista, Friendship Boats):
Lastly, here is Walkthroughs:
Final tallies using my count:
Rides: DL 47, WDW 45
Shows: DL 10, WDW 26
Vehicles: DL 7, WDW 6
Walkthroughs: DL 5, WDW 5
TOTAL: DL 69, WDW 82
Disneyland packs a punch with rides, but WDW beats it handily with shows, exhibits, shops, restaurants, etc.
