1. Helium is a non-renewable, finite, natural resource with important medical uses.
2. Hydrogen provides more lift.
3. Hydrogen molecules are bigger than Helium ones and they leak out more slowly.
On the other hand... hydrogen does require more care in handling. Helium is an inert gas so doesn't burn or explode. I'd like to say completely safe... but people would start imagine ways for it to be dangerous such as breathing 100% helium or the potential dangers of anything under high pressure.
