I don't know anything about the Reef Octopus... The Vectra I can speak for, had it for a month. Hands down best pump I've ever owned - heck nothing even close actually. Never a problem restarting. Is actually quiet. The controller at first I thought was a bit of a gimmick but its turned out handy. The hardware is Allen head not screws! No vibration. I am running it external. Only complaint is the use of British standard fittings, but off the shelf PCV bushings glued in (can send closeups of this).
