What is the Best and clear BIOS or UEFI you used ?

UEFI also determines what operating system or system components to use.

I prefer computers that just use BIOS.

If I have to use or work on UEFI computers I prefer Dell computers.

UEFI and BIOS are utilities used in the boot process of  electronic machines such as computers . UEFI  performs better than BIOS is most instances

UEFI works with the BIOS to initialize the computer or tablet's hardware before handing hardware control over to the operating system. UEFI can also load and display software programs from storage devices to provide even more functionality
