The main consideration for the recommended parks on Touring Plans is the EMH schedule. They do not recommend parks that have EMH as they tend to attract more crowds.
Touring Plans does this because of the reasoning that many people do not get up early enough to take advantage of morning EMH (or stay up late enough to get the real advantage for evening EMH). If you're early risers and know that you'll be at the park for opening, it is recommended that you do EMH and enjoy the park in the morning. When it gets more crowded around late morning, hop to another park for the rest of the day.
I am a big fan of the touring plans website (and their related podcast). However I never really look at their 'best parks' -- solely because we are early risers who are at the parks for opening, then hop to another park in the afternoon.
Hope that helps!
