Most similar cassettes use the same sprockets, and the difference is in things like plating or other cosmetic details.
Sometimes more dough gets models with the larger sprockets on aluminum spiders vs. sliding directly onto the freehub. That feature is worth paying extra for because it reduces nicking of the freehub body. There are also generational differences with new cassettes having more aggressive shift gates for crisper shifting.
If you can't see any specific feature that justifies spending more, but the cheaper cassette.
