* Unfortunately, I no longer have Oasis or KOBO-FORMA for photo comparison.
But I owned both devices and the form had better contrast and fineness of the font..
.. Compared to KOBO-LIBRA vs Oasis, OASIS is of course better on that.
Thanks for comparing  |
Best of what I've seen to worst, just text, without built in light:
1: Original H2O, though slightly lower resolution.
2: About equal: PW3, Kobo Libra and Likebook Mars
3: PW4, but fine if you've not seen the others.
I've not seen the Voyage, Oasis or Forma.
The Kobo Touch I had was dreadful with ghosting, Kindle DXG, older Basic, and KK3 all better.
The Nook Touch and PRS-350 similar quality and not quite as bright as the DXG (which uses a later screen than DX, which (I've not seen) or the KK3. All five of those are fine to read.
I did see the originally launched Sony in Dublin (maybe the 2nd model?), it was very grey and too expensive. But wife or I would have bought it to read Gutenberg texts if it had been cheaper. Tedious reading on 2002 laptop or CRT back then. Maybe 2006 or 2007.
Anyway with ambient light good enough for a paperback, any of the DXG, KK3, old Basic, PRS-350, PW3, Original H2O, Libra or PW4 are fine to read on. The DXG, KK3 and old Basic are slow and too low resolution. The 5" PRS-350 is nicer than a 6" phone. I found the slightly lower resolution Original H2O far better than the PW3 due to 6.8", annotation export via Kobo Utilities, series and collection management. The 300 dpi 7" Libra was the best over all, though not just as bright under ambient as original H2O due to better speed, easier to do selections and higher resolution.
The Mars was cheaper than the Forma and bought as a luxury to enable direct County Library access (Borrow box) via Android app. It's also better for PDFs.
I bought the DXG for PDFs, but despite 9.7" it's too slow and too low resolution for image based PDFs, the original H2O is better.
Cost here:
Cheapest is Mars, next is Forma and Oasis is the most expensive. Libra is cheaper than all three. Also the Kindles are poor at collections, series, annotation export compared to Kobo. You can load older firmware on a Kobo, but not usually on Kindle.
So I'd not buy an Oasis over a Forma (or Libra even) if the screen was a lot better. I find it hard to believe there is more than a marginal difference between any current eink that's 300 dpi.
