The first PPA is called "Kubuntu Backports" and the second PPA is called "Kubuntu Updates".
Which one of those two PPAs should I add to Kubuntu/Ubuntu in order to get the best and the most up to date KDE Plasma? Or should I add both PPAs?
In GRUB Kubuntu 18.04 LTS is named just "Ubuntu".
Here's part of tlp-stat output (Kubuntu 18.04 LTS is named here "Ubuntu 18.04 LTS"):

I'm dualbooting Kubuntu 18.04 LTS with Windows 10. I was dualbooting Ubuntu 18.04 LTS with Windows 10 before. I replaced Ubuntu 18.04 LTS with Kubuntu 18.04 LTS by formatting Ubuntu's partitions (swap, / and /home) and installing Kubuntu on them.
Did I mess something up? Should names "Ubuntu" instead of "Kubuntu" bother me? My biggest concern is TLP not recognising Kubuntu properly and consequently not handling battery life as well as before.
