I like the DBE because of the clarity on the glass and the fact that it's rimless, but I am losing some real estate because of the depth on the overflow. I used to have a 65g RR with a center overflow so I already know how much space I am going to be losing. If I go that route then I can just attempt to create a two-island scape. If I go with the standard 75, that will give me a lot more room to aquascape, but I won't get the rimless look and clearer glass. Hmmmm....
