The posts about the 5" Astak Pocket Pro's "screen" are really about fonts. The problem is that the default anti-aliasing of some fonts does not work well on E-Ink screens with 8-16 greyscales. Fortunately, the 6" EZ Reader Basic (Hanlin V3) only has 4 grey scales and the font issue seems to be much reduced. I think the same is the case with the PocketBook 301+, although language barriers make this difficult to pin down. Certainly, a standard EB600 only has 4 grey scales in hardware (but now there are updated versions with the Epson controller and 8 grey scales).

I have seen claims that the PRS-505 has the best 6" EInk screen, but so far as I can tell the actual screens of all the major brands are identical (and all show variation from unit to unit). What is different is the fonts and display software. Sony does seem to have worked out how to use 8 hardware grey scales to their best advantage, so the PRS-505 might be a step above the 4 grey scale devices.
