Vacation experts (Destin or San Destin?)

Are these places one in the same or is there a difference? I've only been to Destin one time and it was last year for a couple of days. I rented a condo and it was pretty decent, but i wasn't exactly blown away by my first Destin experience. I guess i expected more, since i've heard so many great things about Destin, since i moved to Louisiana 6 years ago.

I've been told that San Destin is nicer than Destin, but i'm confused if both places are one in the same and people just call them different names.

Can anyone help me out with an explanation or suggest a nice condo/resort in the area i should stay at?

Thanks in advance.
