I think the novelty wore off these pickups. When there were only EMG's these were refreshing enough and as close to passive as you could get in an active format. A lot of guitars started appearing with them and a lot of people replaced their EMG's with them. Then slowly and with the rise of djent and Bareknuckle pickups they were suddenly muddy trash or the people that were tuning really really low finally understood their limitations. Also when Blackouts came out it was all about super output pickups in metal that destroyed the world. And these delivered. I've gotten tge meatiest tones out of the Blackouts and they made E standard sound like what you'd expect from lower tuned guitars. As an example the Nazgul up until recently was one of the highly regarded pickups and there have been a lot of people lately that hate them with passion.
