What's the difference between the Jebao PP's & RW's

[cracker]

Other than being newer , I assume is more sturdy .Are there more functions or such?
No big deal just curious . I have 2 PP 8's along the back of my 6ft 180. & would like a 3rd.
Iv'e had the 2 for over a year & they seem to be working fine,

Flow patterns too I belive.

OW is newer, has 4 way magnet and can run at lower speeds and is quieter at least that's what I remember. I have 2 PP-8 pumps in a 4ft 75g for 7-9 months and like the bang for the buck.

The rw's's are are only 20 bucks more so I think will do some more research.Yet all I want is one for the back of a longer tank. decisions, decisions ! I have no complaints over these W/M's . Certainly con,t beat the price,,
