I am running a Fluval 404 on a 550L tank, absolutely no problems at all, good flow rates, even when the filter is dirty.
Yes you do get good flow rates on the Jebo as well, but at the end of the day you are paying for quality with the fluval. Eheim etc.
Another option is the Aqua One cannisters, not much more than the Jebos, and would stand a little more punishment
Bottom line, you get what you pay for
