Never used redshift only to see what the heck it was.
I will be honest I didn't know much about kde as only had experience with gnome and cinnamon, when plasma 6 dropped I decided to look into it, and ended up liking it a lot more than cinnamon.. Didn't feel like setting up/downloading things again when distro hopping so I back ported kde from kubuntu.
