Tennis is definitely better in terms of aerobics because you run a lot more, but if you absolutely love golf then go for it :)) I'd say playing sports with your friends is so much more fun though, tennis will make you happier than golf from the information you've given :D
Hope you do well in either sports (:
Well if you know Tennis and you have friends in Tennis then why not play Tennis? I would stick with what I know and play with friends as well as make new friends.
