I'm really liking them and they go well with the other hops. I used the Equinox at a higher proportion and it has a nice fruity flavor and aroma.
I love Equinox and I love Citra, but I didn't like them together that well. They kinda clashed to me. As the beer got older, it started getting better.
That amber pictured above was hopped with equal parts of Equinox, Simcoe, Columbus, and Centennial... It's a resinous dankity-dank bomb.... Seems like Equinox and Columbus would compliment each other greatly.
