I bought my first jebao pump back when I was broke and wanted something other than maxi jets! I used that pump for a very long time. Right now it's in the sump moving water for the cheato. That pump has been plugged into the wall running for 4 years. Then a quick break before called back into duty. I have had several since then and none failed on me. They are cheaper than the fancy expensive stuff. If treated well and cleaned regularly they seem to last. For me anyways.
My new build I was lucky enough to buy all high end stuff. Mp40s and maxspect gyres. They are nice and pretty and work just as well as the jebaos. They will probably outlast the jebao.
I suggest getting the jebao. Then you can save up for used equipment or new if your not happy. If my return poops out it will be a jebao. My dosing pump is jebao.
I have steered clear of the crossflow. I have no reason for steering clear though.
