I own both a Libra 2 and a Libra Colour, and after roughly six months of real-world use I exclusively use the Colour now. My personal use-case is reading b/w text mainly at night, and colour Manga.

Colour Manga/Comics are an absolutely joy. I can't overstate how wonderful it is to read full colour Manga on e-ink. Similarly, seeing full-colour book covers on the homescreen and lockscreen is wonderful - it's not 'necessary' by any means, but it is a surprisingly nice feature nonetheless.

For b/w reading, yes, side-by-side KLC vs KL2 there is a difference that I'd characterize as a slight 'graininess' to the black and white text. I took some side-by-side pics in the original poll thread for folks, and yes, the Libra 2 is objectively better in contrast, brightness, and whiteness quality. If you're exclusively reading B/W text and you don't find any interest in having colour covers, colour lockscreen or any of those small touches, then Libra 2 is the best possible screen IMO.

But, I don't read on two separate devices side-by-side so it's not a constant comparison. I use one, or the other, and in both cases the device is meant to fade away and let you read. And, reading b/w text on the KLC is not only just fine, the overall experience of reading on the colour is the better experience. For me, that comes from the response time and overall 'snappiness' of the device itself, colour covers, a just-fine b/w reading experience, and joyful colour experience.
