No, have not actually compared them to others. I use them in my opinion for less important places in the chain. In my example ISP/fiber in and main router. 12volt and 19 volt for my Asus router. For my so to speak more important duties I use Paul Hynes and Sean Jacobs DC-3 and DC-2 so I guess it depends where you will use them.
But they seem well built and are very reliable and silent.
