I've not touched oklch, but I've played with oklab gradients a fair amount.

How do they (oklch & oklab) compare for different uses?

oklch uses the oklab color space.

[cluckindan]

The oklch color space is polar: it’s a cylindrical transformation of the oklab cartesian color space.

[raincole]

That's quite misleading. The parent commenter was asking about gradient (interpolation between colors). Gradients look completely different in oklch and oklab.

[tovej]

Well yes, it's a different coorsinate system, so gradients would look different. It is still the same color space, but I agree I could have worded that better.
