Yes, it's a matter of preference. (looks, etc.)
FYI: My 400 gallon is a FO tank.
As said, you do need very efficient biological filtration. And, decor is also needed for the fish. I prefer coral skeletons (not fake) since they also keep the Ph in it's ideal range (I never need any buffer).
Mine is a large w/d filter which keeps ammonia and nitrites at 0 all of the time.
My nitrate filter keeps nitrates near 0 (with heavy feedings, heavy bioload, and no water changes in 6 months).
