Hackintosh allows you to have OS X on better hardware but these days it's really unsafe, due to the possibility of Apple going full ARM in the near future, dropping all the support for x86.
How is it different than buying a Mac now? It also won't upgrade itself to an ARM processor and they'd need to support existing macOS installations for a while anyway.
When / if Apple stop support for x86 any Apple computer purchased before they go ARM will essentially be end of life.
If you do not want to build a hackintosh because of ARM in the future you also do not want to buy a Apple x86 computer today.
