Not really. Both are all over because they address vastly different (literally incompatible) needs. There is a fair bit of industry hype in the past decade or so around eventually consistent systems, because a lot of components of a business can use them, and that opens up a lot of extremely desirable performance options that can be fine tuned to the moon. But they're a real nightmare to use (i.e. often literally impossible) for anything that needs to be correct, so they are often just used in addition to the more classical consistency-oriented databases like postgres.
