Which is better BCD or binary?

Could you please clarify for me which one is superior, BCD or binary? I'm trying to understand the nuances between these two numerical representations. Is BCD more efficient for certain applications, or does binary excel in specific areas? Also, could you explain the advantages and disadvantages of each? I'm interested in learning about their respective performances, ease of use, and any potential limitations they might have. Thank you for your help in shedding some light on this topic.
