• Related滅びるほろびるNeutralUsed for the fall or ruin of nations, species and the like — its objects are groups or things, not a rude way to say an individual dies.
• Related果てるはてるWrittenA written, formal word for coming to an end or dying; also a suffix meaning 'utterly', as in 「疲れ果てる」. It lacks the vulgar ring of 「くたばる」.
• Related死ぬしぬNeutralThe plain, most common word for dying; it can also mean losing vigor, but carries no cursing or rude tone, unlike 「くたばる」.
• Related消え失せるきえうせるNeutralMeans to vanish or disappear, and can also mean to die; often used to tell someone off, as in 「消え失せろ」. 「くたばる」 is about dying or being worn out.
• Antonym生きるいきるNeutralAntonym: to live or survive. Neutral in tone, with none of 「くたばる」's coarseness.

For dying, the default is 「死ぬ」. Reach for 「くたばる」 to curse someone — 「くたばれ」 — or to say someone is worn out, as in 「すっかりくたばった」. The others cover vanishing, the fall of nations, or formal and literary ends.
