Valid arguments for both, they both can fail if clogged obviously.

But the External Overflow can also fail if it loses it's syphon when trying to restart after a power outtage.

I regret having an external overflow, it's a constant fear of flooding (happened a few times). I wont make that mistake for the next tank.

Regarding the sump, you would want a sump from the start. That's where you keep all the equipment (protein skimmer, heater, filter socks, media reactor, maybe a section for chaeto, etc.).

LOL...
My friend, I live in no such fear.
You must have one of those CPR units...lol
And you realize you just stated that neither format is actually 100% flood proof right?

Go with a Life Reef or similar.

Again, 6 years, no breaks in siphon, no floods and probably 100 power outages .
