Mutianyu vs Jinshanling -- Early October

I'll be visiting the Great Wall on October 7th. It seems that this is at the end of the Golden Week. I'm trying to figure out if Mutianyu would be too crowded. In this case, I probably will go to Jinshanling. On the other hand, if Mutianyu won't be too crowded, I guess I prefer it (since it is closer, and less time will be spent in transit, etc.).

Any thoughts?
