Snowboarding or skiing? Which is harder?

Ok so I started skiing when I was 3 and my brother 2....By age 5 we were able to hit blacks and Moguls! When I was 8 I switched to snowboarding. By age 12 I have skied down the continental divide and back country. Honestly skiing is easier to start with because you can maintain speed and manuver easier. Snowboarding is harder to start out but after that skiing and snowboarding are pretty even!
