Oh yeah, no arguments here. WDW is the better resort. You just can't get around that at all. You can't spend 7 days at Disneyland Resort but you can at WDW. In fact, maybe you don't squeeze everything in there in 7 days. Obviously DL is an experience too, but they lack the space that WDW has. WDW has its own bus transportation. It is just so grand that it is impossible to beat from a mere vacation standpoint. The monorail ride from Epcot to WDW is so nice as well. I just feels like you are being transported to another place. And another thing is that no matter how high you are on a ride you can never see the outside world at any point. You just literally think you are in a park that has trees surrounding it.
So for that I give the nod to WDW. You can spend more time there for sure. I think the nostalgic factor wins out in Disneyland though. Just lots of history, Walt's apartment, the Main Street Cinema, Mr. Lincoln, etc. That's before you even enter under the castle. I just think Disneyland is the perfect theme park in so many ways. Just like when you are in WDW you never ever think you are in a theme park but rather a fantasy. I don't know how Disney does it. But the park itself is about as close to perfect as you can get.
In my honest opinion, I think when you are at either park you miss things from the other park. But you aren't down in the dumps about it because there are things at each park that the other doesn't have, so it evens out. That's my feeling at least. You never feel anything but that Disney magic.
