Hellfest compared to Graspop; is it worth the extra cost of travelling from The Netherlands?

So this year I visited Graspop and the line-up was practically the same as Hellfest but Hellfest seems to have better quality surrounding, coffee and food. So I like the decors and a different surrounding once can be nice as well.

The only problem it will cost me a plane ticket of 300 euros... If the line-up is the same is it worth that money?
