At first for Different Sense I was a bit overwhelmed considering it's essentially a wall of noise coming at you full force, and personally I'm not fond of Kyo's guttural ranting/pig squeal mixtures, they just don't have much force behind them (the death metal sounding back-of-the-throat shouting) I prefer the full on insane screaming in Saku, if he has to scream.
Having said that, as soon as the first chorus kicks in the song becomes a whole other beast, and it's pretty much the best of the kind of sound that DeG have been working towards these last years, and I really enjoyed it as well. In a similar fashion, I saw the PV and thought 'wtf, tentacle rape, really?' but it has grown on me very quickly, the grotesque imagery/facial makeup and overall mood reminds me of earlier DeG before their PVs became more minimalist and featuring almost no close-up shots of the members besides Kyo himself. So I appreciated that too.
As for Tsumi to Kisei, I can see how it can be considered boring, and it would definitely fail as part of an album, but I think musically it's very interesting, it has an overall sense of foreboding/impending doom and the general feeling/sound it creates is quite sophisticated (despite it essentially being Kyo's guttural noises throughout) This one is more an experimentation with sound and feeling as opposed to your generic music track.
I didn't listen to the live.
I'd give it a B+
I anticipate the album greatly
