Hi Dr. Flem, and welcome to the forums...
I did a little goju ryu back in the day and quite enjoyed it, and my current instructor started out in wing chun, and has been happy to pass on his knowledge and experiences, although it will not be the same everywhere, the place I studied goju ryu was quite sport orientated and the practicel self defence side of it took kind of a back seat, as regards wing chun, I am led to believe that in and of itself it is very practical art, if somewhat repetetive in the start.
With all that said though, I personally would reccomend that you check them both out and decide for yourself after seeing what they have to offer as compared to your expectations and what you want to get out of it.
Everybody has their own opinions about specific arts, but I believe that there is something for everyone out there, and it is not the style, but the person that makes the difference.
Good luck whatever you choose, and welcome to the wonderful exciting world of the martial arts.
Best of luck,
