You've been comparing two options but how often is there even a choice? I mean, how often is EFI available for "embedded" hardware? (conversely: how often do servers support u-boot)

Pretty much always nowadays on devices that matter (ie, have been built from ~2010 onwards - if you are doing retrocomputing on CPUs from the 70s, 80s or 90s that's great and hope you have the best of times, but out of scope of anything I care about), as uboot can be configured to provide a UEFI interface, allowing one to be mostly free of the pain of dealing with it. Or at the very least, delegate all that pain to the firmware team, and be blissfully oblivious from the bootloader and OS viewpoints ;-)

UKIs can easily be used with other early boot systems. The main complexity was in getting everything that is needed for boot to be properly measurable.
