F-15E, worth it or not?

Every F-15E I've seen has gone negative and see them dying in the feed. I usually prefer 10.7 to 11.7 but have played 13.7 with the Gripen and F-16C and it's not been the most enjoyable. I'm thinking the F-15 might make it more enjoyable but I'm having second doubts. Is it worth it to fly it out?
