Things vs 2Do

Hey guys,

I have Clear for Mac and iPhone, and love it, but for more in depth tasks I could do with something of a higher level.
Having looked at both the Things Demo and the 2Do demo, I don't really know which ones to choose...

Could you shed some light on the matter and tell me about your experiences with one, both or the other and why you went for one over the other, bearing in mind that I am getting the app for both Mac and iPhone

Thanks
