I've tried 3 vortechs over the years, and found them all way too loud. The dry side(motor) could easily be heard in another room 15 feet away. Other tank noises will easily mask it, like fans, skimmers, etc- but I set my tanks up so they are silent.
The Tunzes give comparable wide flow with the 6205 grille upgrade. They are alot quiter than Vortech. The wider flow of the Vortech doesn't pack alot of punch towards the end of a 6+ foot tank, The Tunzes have a narrower flow, depending on which shroud is used. Tunze take up about twice as much room in the tank as the Vortech wetside does. The wires and pump are easily tucked into a corner out of sight- tanks with top bracing will have more noticeable wires.
The Tunze is a bit more reliable than Vortech, especially given the nature of the way the Vortech operates. But, you cannot go wrong with either- they are both high quality and have outstanding service.
