I got the 1080s. Tried them in the shop and they felt good, but then wore them for Parkrun and found the upper (the thicker "saddle" bit that the laces go through) was digging into my toes as my foot bent to toe-off. Other than that I liked them - initially they felt a lot firmer than Hokas but I liked the feel by the end of the race.
Not sure if they'll soften up in the upper. At the moment they look like an expensive mistake.
I think the Pure Cadence has been dropped by Brooks, so you may have no choice anyway. Options could be Pure Flow, or Saucony Kinvara which also has a 4mm drop. Hoka do too, but they're quite different.
