I have a Voyage and a PW2 and I can't really see much difference in the screens. Actually I can't tell the Voyage is higher definition. I've turned off the Page Press because I prefer swiping. I've turned off the self adjustment feature on the light because I don't need it. So my Voyage is a smaller, lighter, easier to hold Paperwhite.
And that's what I love about the Voyage. I'll probably read a bit with the Paperwhite today to give it a second chance but I've been thinking about getting a second backup Voyage and I don't expect this to tempt me away from that. But I'll let it try.
