In Korea, the sweetpotato on the left is 호박고구마(pumpkin sweet potato) and the one on the right is 밤고구마(chestnut sweet potato).
They're different in texture, taste, moisture, etc.

I'm curious if there're these two types of sweet potatoes in western countries too, and if there are, can you guys tell me what they're called in English?

Personally, I prefer 밤고구마(right) to 호박고구마(left)! Which one do you guys like?
