Well when you say F-15 I assume you mean the F-15 Eagle and Not the F-15E Strike Eagle. If so then...
The F/A-18 Hornet. She is the best multirole fighter on the list. She has a higher payload than the F-16. Can buddy tank (something no USAF fighter can do), and carries the highest number of AAMs (10) of the planes listed.
But really the F/A-18 and the F-16 are the only planes it far to compare. The F-15 is an Air Superiority fighter designed to kill other fighters, the F-14 is a Fleet Defense Fighter (a navy way of saying Interceptor) designed to kill missile carrying bombers. The 16 and 18 are the only two multirole fighters on the list.
