I have both, I use the 2 fathoms for home theater and the 2 rel's for my 2 channel. found the rel was easier to integrate due to the speakon cable and the remote is awesome. the fathoms are more compact though which was easier to place in corners and such. sound wise its honestly apples vs oranges. the rel enclosure is wood which to me gave a more musical sound, but the JL are nice and powerful. if it was a home theater decision it would be fathom no question.
