And because APFS is written from ground up with SSD in mind, it might not be the best idea to use it with spinners. Because spinners need a DiskWarrior every now and then and APFS does not support those mechanisms.

Well, you might think I still use spinners, I don't unless for cheap backup purposes.
The fairytale never having to "defragment SSD storage" is not true.
Anyway, I use Samsung M.2 NVMe SSD's, all sizes between 256 GB to 2 TB.
The fairytale about APFS being the ultimate solution for SSD is something I will not buy. Since using APFS I had more trouble than in 30 years of using Macs, which is why I went back to HFS+.
Since having tested APFS extensively on all of my Macs startup is slower, period -and I do not startup from an NVMe as I know the speed they offer does not help for starting up. I investigated all this to death.
I am using HFS+ still and all is fine. Odd, right?
