Helghast (killzone) vs Sanghelli (halo)

Which is the tougher and rougher race.
 
Which would win in a battle? 100 higs or 100 elites in a jungle, with both sides running into each other?
 
Sanghelli are elites by the way.

Elites win this. Stronger, smarter, faster, better tech, and better tacticians.

Elites easily

Elites win.
