Easily the best of the bunch. Foley has GOT IT, he can GET IT, it is GOTTEN ever more. It felt like a celebration of the Wilderness Years, having that sort of weird ambitious vibe. Unlike the other Once and Futures, it took its characters on journeys and did interesting things with them; I especially liked the Vienna bit, doing something different with BF's best character.
Also, the teases to the future were genuinely hype. It's very thrilling seeing the writer weave such a tapestry across his work.
