What is the difference between cave spiders and regular spider loot?

According to the Minecraft wiki they do drop exactly the same thing. Their loot includes the following:

• 0-2 String
• 0-1 Spiders Eye
• 5 Experience

However, cave spiders have 12 points (6 hearts) of HP whereas spiders have 16 points (8 hearts), yet cave spiders are still poisonous. This is why it may seem easier to kill cave spiders.
