TDL blows the MK away in every significant category I can think of ... by a HUGE margin. Fanbois would simply wet themselves if they saw a park that clean, that well maintained, that full of attractions and always fresh entertainment (like say three parades shown a total of five times in one day) with every eatery open and no merchandise out in walkways while shops become storage facilities.
I don't think for a second that the F-land rehab (hate the word expansion because it really isn't when talking about space and capacity) will do anything beyond making the MK a lot nicer place to visit.
Right now, the only thing preventing me from placing HKDL above it is the lack of attractions (I am now a proud HKDL APer, for full disclosure). It beats MK in cleanliness, show quality, CMs, food quality and price, and entertainment (especially seasonal). And I'm more excited about the two new E-Tix coming (as well as the lands they'll occupy) to it than I am for Mermaid (which I can ride in Anaheim), a short SW mine train and Dueling Dumbos.
