Quality of life here a bit south of Miami is quite good for adults, probably a little less so for kids. I only drive to work once every week or 2 though, and work from my back porch garden area. I usually don't have to deal with the bad traffic. So my experience is not typical in terms of traffic.
Better money opportunities here for many people (depends on what you do), although costs of living and real estate are high.
There's lots of cool stuff to do here. I can go snorkeling, diving, kite surfing (haven't tried yet), biking, kayaking, fishing, and adventure out in the boonies or the Keys (not far). South Beach and Key Biscayne are close, as is downtown. Concerts, plays, museums, art galleries, and events. This weekend we have Chocolate Fest at Fairchild, and Chinese New Year fest at Smorgasburg, the mass food truck event they have every weekend around the graffiti Walls of Wynwood.
Restaurants! Many good ones.
Oh, and lots of growers nearby, with all kinds of fruits and ornamentals.
Think I need a mountain home too, but I really love it here.
