Hi CreoleHottie,
Jax is a nice city and you'd probably like it.
It is diverse, moreso the closer you are to the city center or the beaches, so I would suggest living in one of those areas as opposed to the more bedroom communities or rural areas.
You'd probably want to check online for employment possibilities, others would be better than me at suggesting places to look (Monster.com, that kind of thing).
You might want to make a plan to visit the family member in Daytona and then driving up to Jax and spending some time here, that will give you some perspective on the two places.
Overall, you will find better employment opportunities in Jax, and that alone may end up being a deciding factor between the two.
The weather and beaches are great.....you rarely hear people in Jax complain much about either
