It has all of the benefits of a wet dry...without the loss of pump head associated with pumping water up from a sump: really flexible, effective and efficient. Another advantage is that, if you're lighting the tank itself, you can dedicate a portion of an in-tank sump to nitrate removing plants (without setting up separate lighting) for them in a separate sump or refugium. Also none of the complications of overflows, etc.: water overflows in, water gets pumped out...
The trade-off is that you have to dedicate some of the tank to the filter area. With a massive tank, dedicating enough volume for an in-tank sump (or two) is inconsequential...

How is the in-tank sump idea the best? I can think of several reasons why it isn't, but would like to hear your logic on this.
Interesting. I do have a section of the tank that is obscured from view. I could make a 98x24x30 internal sump (305 gallons) and build caves under it. Sweet idea.
