Expanse battles were far more realistic of course. The B5 Star Fury combat scenes were pretty ground breaking for the time though. Expanse ships (at least where I'm at in the book series and show - kind of early) are a lot closer to current human tech of course. In B5 humanity had tech that was mostly believable (still used rotating mass for gravity), but you got to see some very unique looking ships from the other species like the Minbari and Shadows that truly looked alien and unsettling.
