We all have had this discussion before and it usually seems to cause issues between people. Here is how it goes to simply put it, WDW is an Orange and DLR is an Apple, their both wonderful and very different, you really cant compare the two.
Disneyland pay much more attention to details and the cast members always usually seem to be nicer than what Ive experienced at WDW. Disneyland has the same amount of rides as WDW but just in two parks, not 4. However, WDW has 4 parks, almost 30 themed resort hotels and water parks and a bigger DTD, this doesnt mean Disneyland’s DTD isnt nice, like I said before, its just different. Disneyland’s Monorail acts more like an attraction than a mode of transportation, it does take you from Disneyland to DTD but thats it (the resort has plans to add another stop in the Grand Californian in the near future)…Disneyland is known as a “Pedestrian Resort” In Company terms since you can walk everywhere and dont have to deal with the Ferry’s or the Bus System, not to say its not nice that WDW has that. I prefer the weather at Disneyland too…but Im a Californian boy…never been one to like Florida weather much. Disneyland is also going through a VERY large expandsion project right now as well, expanding and re-doing DCA, re-modeling the DL Hotel and a DTD expansion is on the way along with 2 new hotels, another parking garage (thankfully!) and eventually a 3rd Park property after everything is done that is currently going on (looking at 6-8 years down the road, or so Ive heard).
Both resorts are very Magical and Wonderful, their just different. Period.
