Have used all three at this point and they all have their good and bad.
Vortech - loud as hell, good wide flow, small form factor
Tunze - reliable, super narrow flow, silent
Jebao - very good flow from any model, silent, hit or miss reliability
So take your pick, Ive had mostly Jebaos throughout the years. After getting the more expensive powerheads, I do not see the need for them. The same can be accomplished for a much cheaper price. While the vortechs are good, they cost too much to rebuild them, and the cost of parts are much higher then a rebuild from jebao and tunze. Why pay $75 for a new wetside instead of getting a new impeller for less than $10 from tunze or jebao. Have used, wp40, wp25, rw4, rw8, rw15, mp40, tunze 6125. If you keep up with maintenance on the jebaos, they will last. The wp40 ive had for 4 years now still runs, but needs new ceramic bearings. The rw15 is the only one that has completely failed on me and it is the newest one, purchased last year. All other are chugging along.
