I think they're really good. Live I had no idea what to expect when I saw them opening for Gojira, but I have a facination with feedback so I enjoyed it. On album their songs can mostly sound the same. The songs that do stand out (the City, Teach, Giveth) are really cool. I really enjoyed the Wars and Rumors of Wars album, the Long Live album got a lot of praise but I found it was full of those songs that all sound the same.
I can see why a lot of people wouldn't like them though.
