What Express Pass should I get for Universal Studios Japan?

My group of three plan to go to USJ in October. Today at 8pm would be the start express pass sales for the exact day we plan to go.

I’m not sure if I should go with Klook or the official USJ website to get the admission ticket and express pass.

Would it be better to go with the express pass 7 or express 4? We plan to go to Super Nintendo world.
