All that matters mechanically is that it's long enough and the width is compatible with the cranks and cassettes, ie. 8s, 9s 10s etc.
Other than that, you can spend differently for some improvement in both overall quality and cosmetics. As a rough rule, there are mechanical quality differences between lower and mid range chains, but the differences from mid to top range are mostly about weight and cosmetics.
One word of warning, many mega drivetrains need chains longer than the typical 112-114n links, so you might need two chains
