Autechre, never really got into their music. There are some really nice tracks for me, but out of the more accessible ones. It seems like a lot of artists are considered "brilliant" because they are making very complex/complicated music. But emotion is also important. Or a certain groove. A lot of Autechre stuff sounds to me like it would be a nice effect to implement it in a DJ Set and it is really impressive what they are creating sound-wise. But I prefer a certain kind of catchiness. Maybe that's why I like Aphex' stuff more. Does this make him more brilliant? Maybe. Maybe not. In the end all a matter of taste.
