I'm not really a big fan of the Daft Punk comparisons. Superficially the fact that they are French and have that Retro-Future kind of aesthetic makes them comparable, but beyond that I see few similarities. I find many Daft Punk records fairly structureless, which is quite a contrast to the rock structure of these Ed Banger bits. Also, Daft Punk rely heavily on samples. Not a problem in itself, but vicious repetition of samples in tracks likes Robot Rock and Harder Better Faster Stronger seems to render them a somewhat lacking in direction or progression. This is not a criticism you could level at many Digitalism or Justice tunes.
I dunno, I totally lost respect for Daft Punk after the tour fiasco of last summer. Plus I see Daft Punk as very handbag while Justice etc seem more sleazy/dirty. To me they owe more sonically to Mr Oizo than they do to Daft Punk.
I guess I'm overstating the differences here just for arguments sake, but I've never been a fan of Daft Punk. Henceforth its interesting to try and define why I am more than happy to dance about to SMD, Justice, Feadz etc but not to Daft Punk.
