I was leaning to the Sony 600. After seeing the screen cloudiness, I'm leaning to the BeBook Mini (Astak). I personally wouldn't buy 2 readers at the same time with the technology maturing so fast.
As to the size differential, 6" models have 1" diagonal of marginalia by default. Blank space, progress bar, book title, battery indicator. Not only is the effective reading area 5", but it has correspondingly lower resolution. You can remove this margin on most models (Sony)... but not on Kindle (which I have). With 5" devices, on the other hand, the body of text goes nearly edge to edge by default.
Probably this partly explains why some people say the screen size difference seems small. I'm new and I'm judging a lot by online pics so please correct me if I'm off base on this.
