I won't say one is better than the other. However I do prefer tunZe over vortech. I have owned mp 20 mp40 mp10. All of my vortech pumps required me to send them in at least once during the warranty repair for various problems. The customer service from EcoTech is excellent. Turn around time for repairs are very fast since it is in PA(3to 4 days)
I changed to using a tunze 6055 first and I loved it. It is significantly quieter than a vortech even on full blast or wave mode. Similar modes on vortech pump is loud compared to a tunze. I currently am running two tunze 6095s. These pumps are awesome and with the new wide flow nozzles it definitely achieves a similar effect to a vortech in terms of the broad flow. I have been running the tunzes little over a year. I just had to send one of them In For repair last week due to a faulty power supply. Great thing about tunZes are they have two year warranties. Turn around time was about 1 week having to ship to Texas. Many different flow patterns are achievable, I use my apex to control them.
