In my opinion, there's no comparison to a Wavebox and a Vortech - they are filling different non-overlapping functions. You could make do with one or the other depending on what you are looking for, or even both.

An SPS tank needs massive volume turnover - we're talking upwards of 40 times tank volume per hour - and up. A Wavebox simply isn't going to give you that. A Wavebox will just give you a back and forth effect that will remind you of what it looks like underwater but for SPS it will not be nearly enough on its own.

The more fair comparison is a Tunze stream to a Vortech. To me it comes down to a couple different things: The Tunzes seem to be more expensive, and are directional (ie., you can aim them or attach to a sweeper motor like a Wavysea). The Vortech sits half in the tank, half out. If your tank is inwall then no biggie. If not, then it depends on you whether that's acceptable or not (most people don't seem to mind it though). Also it is non-aimable, however this doesn't appear to be a detriment because the controller is more versatile. The Vortech has a battery backup option, however it looks like Tunze has this option as well (but you need your own battery - it's just a switchable power supply or something). To be honest I don't think you can go wrong with either Tunze or Vortech, they are both top-shelf products.

But if it came down to "Wavebox or Vortech" I'd say go for the Vortech first.
