(assuming the link works correctly) is a comparison between the Nightfall (on left) and Helljumper armors. I think Nightfall has more of the ODST aesthetic you want; canonically it seems to be described as a MJOLNIR-compatible variant of ODST armor. It’s ultimately up to you though, but I thought this should be brought to your attention.
