I did brew with both hops recently. Two west coast ipas, same recipe, hopped with 11 oz/5 G each of Equinox and Exp 6277. I have both on tap right now fully carbonated. I like Exp 6277 better. I like it a lot, actually.
It's bright sweet lemon at first, with a nice fresh grass component. It reminds me of amarillo and a little bit of centennial, but just brighter, more pungent and fruitier. Equinox is definitely more boring. Peppery, a little piney, hints of herbs, like rosemary, a nice hop, but it doesn't stand out for me. I also blended them together when pouring myself a pint, and that was awesome beer!
