What's the difference between soaps like Desperate Housewives and soaps like Days of Our Lives?

I watched both and i think Desperate Housewives is the one that the actor or actress gets their lines down perfectly and Days of Our Lives usually do their scenes in one take and if they mess up the lines they have to think on their feet and correct the lines! Now Desperate Housewives has been finished. So I bought Desperate Housewives seasons 1-8 DVD boxset for another time watching. I love the show.
