I'm glad you like yours. I regretted buying my Clara Colour. It sounds as if we use our e-readers for different material, and that's significant. You like a lot of colour illustrations, whilst I read pretty much exclusively simple black text on a white background. The resolution issue means that when I want to read a book with illustrations (generally non-fiction), I buy it in print.
It's funny that you should raise this. It's only yesterday that someone raised the possibility of replacing her Kindle with a Libra Colour on a Facebook reading group to which I belong. This was my comment to her:
I had a Kobo Clara Colour, which has the same screen as the Libra Colour. IMO, it was a waste of money. The colours are very muted (unsaturated) and contrast is dreadful. I don't normally use the built in frontlight to read, but found that it was necessary all of the time just to get tolerable contrast reading simple black text - even in a well-lit room. The background for a page of text isn't the white that you'll be used to, but grey.
I sold mine on eBay after only a week or so, and took the financial hit. The Clara BW or 2E are, for my needs, much better e-readers.
My advice is simple: don't buy a colour e-reader yet. A *lot* of development is needed before they become worthwhile. (And the same applies to those from other manufacturers, e.g. Onyx Boox. They all use the same screens.)
It's well worth switching from Kindle to Kobo, simply for the vastly better user interface. (that was why I switched a few years ago.) But I'd recommend one of the monochrome models, not a colour one. Unfortunately, if you want a 7" screen, there isn't currently a monochrome Libra. The choices are (a) smaller screen; (b) larger screen, or (c) find a Libra 2/H2O on eBay or similar. (You might get lucky and find a refurbished Libra 2 or H2O somewhere.)
Whilst responses to the OP weren't unanimous, this seems to have been pretty much the majority view.
