Thank you for your review and comparison! Nice to hear someone else's thoughts as I too recently bought the voyage and H20. And I also own the 2013 PW2. I returned the voyage and I'm keeping the H20.
My experience is similar to yours, in that I prefer the screen and the light on the H20. In my case, by leaps and bounds. The screen is gorgeous and warm and, exactly as you said, it really does give the closest feeling I have experienced to paper yet. My voyage screen was unfortunately two toned and uneven which is why I returned it. I also did not like the cold feeling the screen had at all- although, even if it had been even, and not two toned, the cold blueish pink screen tone bothered my eyes and it would have went back anyway.
I'm also surprised at how much longer than battery seems to last on the H20 as well. Quite a bit longer than on the voyage and also longer than on my Kindle PW2. I should say I still love my 2013 Kindle PW2, but the clarity on the Voyage and on the H20 is obviously better with the newer carta screen. I do think the new 2014 PW2 comes very close though. In fact, I prefer the new PW 2014 to the voyage.
I did not buy the official voyage cover, but I did see it in stores and thought it was quite nice. I bought the kobo sleep cover not really expecting much, but it turns out I really like it a lot.
I did initially prefer the smaller voyage screen, but I find I'm now enjoying the larger screen much more and now prefer it.
I do miss small things about the kindle software, like the vocabulary builder and the software is more snappy. Highlighting works much better on the kindles, for instance. Although I find that since I've converted my books to kepub on the h20 highlighting is now much improved.
I personally prefer the flush bezel on the voyage.
Ultimately, for me, the even, sharp screen, the ability to change fonts, font weights, and other customizations are what puts the H20 well ahead of the voyage. I too also love the integration on the H20 with Pocket.
All in all, I think our experiences and thoughts are pretty similar.
I think it's a shame the Kobo H20 isn't available in bricks and mortar stores in the US. I do think more people would be buying it if only they could see it.
Thanks for sharing your thoughts.
