For as long as I have a laptop with an Nvidia graphic card, I'm still going to stick with Pop!_OS. The battery life/power management is excellent out of the box and switching between the different graphic modes just works. As my primary and only computer, I value both these aspects. Pop!_OS has delivered in the past and I have no doubt it will continue to do so.
I have also found it to be more polished than Ubuntu. It included a well-tested dark theme (toggled through Tweaks) starting way back from 18.04. I hope Ubuntu will fix the UI discrepencies in their dark mode.
Looking forward to their upgrade to 20.04. It releases on April 30. 🙂
