Very hard disagree.
It took me half a dozen installs in VMs before I dared try on hardware. I never managed to get the Arm64 version installed at all, due to the cryptic minimalist info the installer gave me, which wasn't anywhere near enough to go on.
I have it on hardware now. It took a day or 2 of work but now it runs it's totally stable. However, the Byzantine partitioning scheme it uses means that although I gave it 32GB of disk, I don't have enough disk space to install Xfce.
It is on a Thinkpad W500, on a ~250GB SSD, multibooting with WinXP64, and NetBSD 10, and both Crunchbang++ Linux and Alpine Linux.
I tend to find that people who praise the installer tell me that it's never crossed their mind to dual-boot and they find it simple because they single-boot it on a very over-specced system where space restraints don't matter much.
