The one gets compared to the other so I watched them both. Both are pared back and tension-making; both good. I liked the aesthetic of Assault (1976), including John Carpenter's soundtrack and the urban western feel, and the main crim (Wilson) is played by an actor with leading-man chops. And I liked that Attack the Block is so much fun, rip-roaring action while also so much full of the social commentary without it getting in the way.
