I have lived in Arlington, Frisco, and McKinney. I didn't like Arlington much due it being older and somewhat run down. I currently live in the Stonebridge Ranch area of McKinney and absolutely love it. Money magazine named McKinney as the #1 place to live in the nation. Allen and Frisco are good too in my opinion. It depends on what your priorities are, though. If you want a big lot or space between houses, it might not be the best place for you. I like the close proximity to lots of golf courses, the relatively higher-class demographics (even at a WalMart at 11pm), and the good shopping, entertainment, and restaurants in the area. Schools are great too. Property taxes are a little above average. Some people view the area as a little snobby, but if you can resist "keeping up with the Joneses" it is great.
