Why Is Everyone So Hyped for the F-18?

Genuine question. Why is everyone so excited to get the Hornet when we already have other planes like the F-16 or F-15 for America?

To my understanding, the F-18 is less modernized than the F-16 and F-15 and when I asked my friend why he is so hyped for it he just said "Because it's an F-18."

Please explain, whether it be that my understanding is wrong or for another reason. Thanks!
