From a users perspective data classes look kind of like a C struct and in particular include type annotations so fit well with type checkers. They also allow for default values and give more control over generating equality, hash, string and initialisation methods.

Comparatively named tuples are an older language feature which essentially allow you to define named accessors for tuple elements. IIRC, these days you can also define type annotations for them.

Their use case essentially overlap. Personally I much prefer data classes.
