Well, it was all on the basis of composition, animation, overall 'catchiness' (I'm sorry, I'm not sure if that's a word.) and all those put together. DT-17 has all those things, but DW's entire theme song sequence was drawn to the beat, which is what I loved most of all about it. I'm not saying that DT-17 doesn't have that 'to-the-beat' sequence animation, but still, I find DW more catchy. This is the reason why I had a dilemma in whether I should pick DW or DT-17.
