well I don't like the wires either and I wouldn't use them in my display, but there are many ways to hide them. My Maxi-jet mods put out 2500gph and because of overheating issues, my Vortechs are running at about 2100gph. Too many advantages of the Vortechs over the Maxi-jet to list here, but there is a considerable money difference for sure.
One of the nicest, cleanest tanks I know of uses Maxi-Jet mods and Koralia 4's. Sure there is more pump in the water etc. but the inhabitants enjoy a super tank.
If you want tro talk about ugly, anything attached to the walls could be considered visual noise including Vortechs. If you want to create a true "slice of ocean", you can't use the Vortechs either. The best large tanks I have seen are all closed loop. You never see any plumbing in them at all.
