Skiing or Snowboarding?

Okay so I've never been skiing or snowboarding. I've always wanted to try snowboarding but I'm afraid I'm too clumsy or uncoordinated to. I'm not very good at rollerskating, ice skating or anything like that because my balance isn't the best. But I'm going soon and I don't know which I should do. I want to snowboard but I also want to do the one that I'll get the hang of the fastest. What do you think I should do?
