Which one should I buy? are they worth it?

Hello, here I am asking another question. Basically, I'm deciding between 2 items and I don't know which to buy.
One of them is a 15% all 9% Luk Osfa suit that is going for around 13b ( no neb or additional pot) and the other one is a raccoon mask with 32 attack 10% all stat. (that's including neb and additional pot).

One answer would be: What is my current Top and Eye acc? I know that helps to decide which I need the most, but I want to know: Are those items really worth 13b? If they are, which one do you think is more rare to come across?

Thanks in advance and sorry for grammar or spelling mistakes.
