Yeah, I've heard really great things about Gig Harbor. One person fell in love with it so much when visiting that when her husband retired she explained that she was moving to Gig Harbor (from CA) and would really love for him to join her but she was going regardless. They both moved and have been extremely happy with the choice ever since.
Gig harbor is beautiful and most anything you want is right there or a very easy commute to the "big city" and airports. Plus the Amtrak is nearby and there's very cool trips down through OR and CA or up to Canada.
It was a a nice nice place to live. Kind of hated to leave but it was just too far from my family at this time (back to the east coast).
