Which tickets should I buy? Circuit of the Americas

I want to surprise my boyfriend with tickets to the Moto GP in Austin, Tx, but I don't know much about the circuit and I don't know what type of ticket to buy.

​

Should I buy the seats near turn 15, the Main Grandstand, or am I better off buying the Gen Admin tickets?

What would you choose?

All your comments will be helpful! Thank you!
