I have ussed both solutions one of my tank was with Mp40 and Mp60’s 6ft tank and the other tank is now Tunze 6095 and 6055 with random flows on the output.
The 6095 is noisy compared to the Mp40 and MP60 at low levels (I actually hear it without any issues) the 6055 dead silent and quieter then the MP40 or MP60.
As for options you have a few more options with the VorTech Controller more time intervals and different flows (up to 12) (example noon to 3 I want lagoon and from 3-6 I want nutrient and so forth) . For the stream groups you do not have that many options(but a future release they said will allow us to have more). I have 4 tunze pumps in two stream groups on 6 hour intervals each where it will go pump 1 random as pump 2 is constant and reverse. I have the opposite going on the othet two pump, with night mode, thunderstorm and last feed mode.
Both options work great you can not go wrong with either option.
