I've been using Nova Launcher to mimic webOS for almost 10 years. I might be slightly too resistant to change!
For not using the default Samsung launcher, which sucks.
Nowadays, even the default Samsung launcher is very customizable and usable. Obviously it's no Nova, but it's not bad.
I like to use non-default apps from F-Droid so it's easier to feel at home on any new device. I do try to only get phones with LineageOS support, but it's cool how much of my usual stuff I can throw on an Amazon tablet or Fire Stick also.
I've been using Nova Launcher since ~1year (after using it like 10 years ago) because Pixel Launcher didn't support double tap to sleep
