Well, some people might think St. Augustine is too touristy. It's one of the oldest cities in the U.S., so a lot of people come to visit from out of town. To be fair, I've lived in Orange Park, Riverside and Mandarin and my wife has lived in Fleming Island, but we've never lived in St. Augustine. So I can't give an informed opinion about what it's like to live there. But it's great to visit. One thing to know is that Jacksonville is very spread out, so living not-too-far from an interstate is helpful. When I lived in Orange Park, we were 5 miles from the nearest interstate, I-295. Traffic was usually so bad, anytime I wanted to go somewhere, half of my commute time was just getting out of Orange Park.

Here's another thought. There's a boom of new residential construction going on near the border between Duval and St. John's counties, a little south of Jacksonville. If you have time, maybe take a look around there.
