We are in central PA, so I can't attest to how this would be in Jacksonville. I have pavers for 16 years, if you install properly (4 -6" of crushed stone, 2" quarry dust, pavers and finish with sand or better yet polymer sand) they will settle very little and hold up for many years.
There are advantages and disadvantages to both pavers and concrete. In the south, you don't have so much to worry about freezing and thawing as we do on the north. So you may want to take advice from people who live closer to your location.
