I don't pay super close attention to this stuff, but it's very obvious to me that not everyone likes Redis; in particular, the kinds of people who have problems with Mongodb tend also to have the same problems with Redis; long-term operational reliability is a big question mark with it.
For my part: on only a few occasions (mostly fuzzer farm stuff) have I ever used Redis and been happy with the decision. I usually regret using it. I always regret using it as an alternative to SQL.
