Being the least bad doesn't make something good. macOS is the least bad choice for the majority of people that just want a machine to mostly browse the Internet, look at their photos, do some light productivity work, and participate in their ecosystem. It also arguably hosts has the best software options for creative work (although that's reaping the fruits of seeds planted long ago - not sure there's much about macOS that makes it inherently better for those tasks these days). For development, its advantage is the hardware it's running on. To achieve any level of customization or to define my own workflow that isn't what Apple wants me to do or to work across multiple systems, I have to fight macOS rather than work with it. Linux on the other hand does what I tell it to do.
