After aquascaping for years, or at least trying to, in 13" of depth I upgraded my 55Gallon tank to 75Gallon with more pleasing 18" of depth. Those 5" made a huge difference and gave me ability to finally create "middle ground." Creating "3D environment" wasn't a challange anymore. I will never go back to "2D" restrictions of 55Gallon tank which at the moment is only being utilized for fish breeding purposes.
