Built in overflows or HOB overflow box?

[edat]

As I get closer into my upgrade I start t second guess previous decisions or begin to think "What if?"
So once again I'll ask for opinions.
I can get my tank with dual overflows in each corner, or I can get without and use a HOB overflow box.
I am using a HOB now and have never had any issues with it.
Which would you get?
I like the look of tanks without big black boxes in the corners plus they take up space.
What is the real benefit of internal overflows?

you can also use a non drilled tank and make a HOB from $20 worth of pvc.

Con:
Internal overflows do take up a bit more space inside the tank.
Pro:
Internal overflows do not rely on a siphon to work and gravity never fails.
The much larger tubing for the overflow is much less likely to get clogged.
With dual overflows and a right-sized pump, one overflow can keep the tank working if one overflow gets clogged.
It's easier to install a Durso overflow with an internal to quiet a noisy overflow.
