I was a BIG fan of Regolith, super sensible defaults and smooth onboarding experience.
But with the V2 it seems the config is now split in 100's of files (ok not 100 but more than one). I loved the fact that with original i3(Regolith) I had to back up 1 file for my i3.
I now moved to Manjaro-i3. Been happy so far.
Settings panel? Check. Keyboard media keys? Check. Automatic display when plugging in monitors? Check.
