The Sanyo got released behind the rest so it hasn't gotten the attention like the others have. Much like last year when the Z2 was talked about more than the AE500, and the Z2 also out sold the 500. Next year, whoever gets out first will do the same thing. I would say as far as all around quality of the units, the Z3 and 700 are pretty much on the same playing field. I bet it would be hard to tell the 2 apart on a "blind" test.
