Freelancer is better if you can find a lot of business. It is less secure though.

If you think you can find a lot of people who want your services try freelancing, if it doesn't work out and you still want to do SEO, try to find an SEO job.

I live in the Washington DC area and there are typically SEO jobs listed. But the salary range varies greatly. I've seen some SEO jobs pay over $100k/year but others that pay $30-$40k/year. If you can make it work as a freelancer, and the rate you charge can be justified by your clients, you'll probably be better off then "working for the man."
