For me it's PeppermintOS.
I started my Linux adventure a few years ago, and haven't owned a Windows PC since.
I currently use Arch on my main rig, and I wanted to install Linux on two old laptops that I found laying around in my house
I then remembered the first distro I ever used, which is PeppermintOS, and I was amazed at the latest updates they released.
They even have a mini ISO now to do a net-install with no bloat, with a Debian or Devuan base.
Sadly, I believe the founder passed away a few years ago, which is why I was really happy to see the continuation of this amazing project.
Excellent - I'm about to install it for my aged mother, because windows keeps moving her cheese.
I want something that doesn't change the workflows once she's learned how to do a task, and that local techs can help her with, and that I can VNC to when I have to.
You can configure the system for backup and auto updates which is handy to keep it secure without any interaction. Only reason I ever had it fail was entirely me screwing it up, usually by distro hopping and formatting wrong.
