I like the Elites, especially the ones with the head gear, like the royal gaurd or something, kickass looking. Freaking hate those damn Brutes, when they do that charging bash thing...ugh...really sucks if you get a plasma grenade on em, and they are running at you, you're all like "Oh shit!!" So you're running too, but you never make it far enough.
I had one head butt me while I was in a grav cycle (forgot what it's called), and it killed me! So, the next time, I got to him and revd up my cycle when we was charging at me and hit him head on, and knocked him into a rock, killed that bitch.
