Yes the Voyage is better in contrast to PW4. Letters look sharper. The PW3 has a little better contrast than the PW4.Also features like more storage and water proof are available on the PW4. Not on the Voyage or PW3. So there is that to consider as well. I have the Oasis 2 and it has a white blue screen similar to my Voyages. I prefer the whiter screen to a tannish one. Some Oasis and Voyages have the white screen and some have a bit of a tan tone. Not by much, but you won't know which one you will get until you open the box and turn it on. Personally they are both nice to read on for me, I just prefer the whiter screen.
