I have used  Hydor, jebao,vortech,gyre and based on my criteria of importance Flow/Programmability/Volume/Price/Design/Durability . Hands down Jebao. It has huge flow,does lack programmability compared to vortech But it's pulse mode can make everything in my cube tank sway,runs silent,it is a little ugly but i can control it's flow direction,and I have never had a single problem with my 3 pumps in 2 years
