I run Pop!_OS on a System76 laptop. Pretty stable, and fast.
I tried pop on and liked it pretty well. Another that was ok and small was peppermint os- I have that on another drive and use it from ti e to time. It’s mainly for,whenever my main drive craps out and I need to get online- it’s all set and ready to go- I just pop out the main drive, and I stall the peppermint os and off I go.
