I run a bunch of decade-old HP Microservers. All BIOS-only.
My personal laptops are old Thinkpads, from before the keyboards went crappy & Lenovo took away the expansion options. So they're all about 15, ?20 generation at the newest, but they are all maxed-out and go like stink. BIOS boot mode optional.
My default hypervisor is VirtualBox, because it runs the same on Linux, Windows and Mac. Defaults to BIOS boot.
This is not like some ancient history. All run current OSes and distros.
Thinkpads were all UEFI since T410 (and related other models), not to mention a lot of non-thinkpad machines since ~2005 were UEFI Type 1 (i.e. "always boot to BIOS emulation mode, but everything underneath is UEFI").
