It just depends on what you like!
I like a sand bed for the aesthetics, trying to mimic the ocean floor. Plus it creates an environment for a diverse amount of microfauna. As well as a home for wrasses & jawfish.
But my current tank is bare, and so will my next tank. Simply for maintenance.
I can see where detritus has accumulated and I can get it out.
I can always add sand easily if I get tired of the bare bottom.
