The vulnerable narcissist vs. the grandiose narcissist. That is, the Hollywood-archetypal "nerd vs. jock", though I have also met some grandiose nerds in my time in addition to the vulnerable stock.

On a different node, I also see that accusing someone of "narcissism" can itself be an expression of envy. If you succeed, you can debilitate someone else with doubt and guilt to prevent them from pursuing what they want.
