What is a better light...Cateye 10 or Vistalight 15?

I plan to start riding at night or early morning, all on good roads but want
good lighting levels as I will be travelling up to 40km/h and I am looking
at
- VistaLite Nightstick Code 15
- Cateye ABS 10 Light

I can get them for about Aus$200.

Any other recommendations are welcome.
