As Hydroguy mentioned, Fantasmic at
Disneyland is far different. The Pocahantas sequence is not at Disneyland. Instead they have a sequence on the Sailing Ship Columbia where Peter Pan and Captain Hook fight it out on the ship. Very cool. And at the end of the show, the riverboat with all the characters is a REAL riverboat (the Mark Twain one, just like the one they have at the MK), not a plywood one. And that special seating is about $65 per person. They have around 20 reserved seats on a balcony overlooking the Rivers of America where you are treated to a great view and some very nice desserts. And then there are more seats (same price as the balcony) riverside with boxed desserts served. A very nice splurge but not necessary to see the show.
Many of the rides at Disneyland are superior, namely Pirates of the Caribbean and Space Mountain. Its Fantasyland is better IMHO although there is no Mickey's Philharmagic. But DL's FL is very charming with many rides not found at WDW. There is also an incredible Indiana Jones ride, same vehicles and technology as Dinosaur at AK. But a better ride IMHO and far better than MGM's stunt show. DCA has a new Monster's Inc ride that is also very cute. I wish that was what was going in at MK where the Timekeeper used to be but its going to be a Monster's Inc comedy show instead. DL does not have anything to rival Epcot or AK but DCA really reminds me of MGM.
Disneyland is compact but does not lack for rides, shows and attractions. In fact at one time, it had more of those in its two parks than the four parks at WDW. That might still be true or at the very least very close to it. DTD is right there, just steps from the parks. And the two parks are about a one minute walk from each other. Park Hopping is something that can be done all day and night long very, very easily. Disneyland is more charming. It has a "Walt" factor. This was his park. Many of the restaurants for instance he ate at and one of them was even decorated by his wife Lillian. So it has a lot of historical perspective that WDW cannot have since Walt died before they ever broke ground.
Disneyland does not have that total over the top, out of this world, resort feel that WDW does. But it has lots of nice dining options, three very nice, deluxe level resorts and many, many nice offsite lodging choices. All within WALKING distance to the parks. It doesn't have as many dining options but it has quite a few and dining can be as much or little a part of the overall experience, just like WDW.
I think all Disney fans owe it to themselves to see the Origninal at least once!
