I would have an open top or egg crate or screen material if you have jumpers. Any glass top like the versa tops are going to lower gas exchange and also reduce evaporation. In most cases the evaporation is a problem not a plus as most of us cool our tanks through evaporative cooling. This also allows people wo
dose kalk to dose more volume.
So basically with the glass tops you reduce gas exchange, and keep heat in; however you reduce evaporation (good or bad up to you), and keep fish in.
If I had the choice, I would have a canopy to keep fish in and hide the lighting. Then there is no reduction of light by using glass tops or eggcrate either.
