I run a mix of Jebao and an MP10 in my frag tank. My display is the MP40 line. I love Ecotech and have had good experience with customer service. There have been recent reports of folks having issues but I haven't head to reach out in a while. In a smaller system I'd go with the MP10 or Nero over the Jebao because they are low profile and look really good. The SOW line is great but it has the look of a more traditional powerhead. If I were in your shoes, I'd be comparing the Jebao SLW to these other two since it's got a much lower profile and I think it looks better.
I believe our very own
@civics14 runs the MP line on his main tank but when I was visiting him a while ago, he had Nero's on the new system he had recently set up. He might have some insight on why he went with one over the other. As far as Jebao goes, it's a lot cheaper but is also disposable. I run some of the wavemakers without issue but if one ever broke, I'd be pitching is and getting a new one. I just checked and my MP40s were made in April 2011 and October 2013 and are going strong. I wouldn't be surprised at all if I got 8+ years out of the Jebao's but I also wouldn't be surprised if they only last a year or two.
