I enjoy them both. I was a frequent WDW visitor for many years because I lived on the east coast and it was cheaper to fly to Florida. However, since moving out to SoCal three years ago for a new job, I naturally started going to Disneyland a lot more.
I think both resorts have a lot to offer. WDW has the 'blessing of size', and as such, can offer many more amenities to vacationers that can keep them occupied on their property for days. Disneyland, IMO has a lot more charm than any of the parks in WDW, and is steeped in quite a bit of history. It is indeed Walt's park and you sense it the moment you step under the railroad tracks and into town square. From Great Moments With Mr. Lincoln to the Storybook Land Canal Boats, there are tons of touches throughout the park that serve as a reminder of its almost 60-year legacy. However, Epcot (despite the many changes its undergone) remains one of my all-time favorite places, and I'll always have a soft spot for the Magic Kingdom, as it is the first Disney park I ever went to at the young age of 4.
Which is better? I don't know, but I think both resorts offer their visitors a great time.
