Depends on what kind of parser you're writing. Parsec is for things that
humans typically write — like programs and config files. When the speed
is not an issue, and good error messages are required. Attoparsec is for
machine-generated formats, where you need performance but error messages
are not so critical.

So there's not that much overlap between these packages, although they
both deal with parsing.
