from a user's perspective, selecting a tool should be about what's "best" for you and not what is the "best" out there (from some arbitrary measure nonetheless).
pandas made sense and might still make sense for many, especially who are migrating from R and are already comfortable with dataframe paradigm. using the same paradigm and just saying "we run faster" does not solve the ergonomics or the reason why people adopted this way of processing data.
there are plenty players in the space going about this from the stack. would be nice to see more discussion on alternative generic data processing paradigms instead.
