grub provides a nice interface for adjusting kernel parameters before booting, which is essential for some installs on twitchy hardware. I don't know of a way to do this in the UEFI boot manager.

I've found it even easier to manage kernel parameters and boot entries in systemd-boot. You can just create another boot entry by making a copy of a text file, and changing the `title` line of the file. Grub is much more complex to manage. systemd-boot entries are very simple text files, so editing kernel parameters is far easier than grub.

  What's the recovery situation? Say my machine is unbootable and I need to tweak the kernel commandline or something to get things working again? Can I do that from the systemd-boot menu like I can with grub?

    Yes, just press E. Just like in GRUB.

  You can edit the kernel entry at boot time in grub, which can be useful when you need to troubleshoot a non-booting system.

    I would add "without properly documenting how to use the framework".

So does systemd-boot. https://wiki.archlinux.org/index.php/Systemd-boot#Keys_inside_the_boot_menu https://wiki.archlinux.org/index.php/Systemd-boot#Keys_insid...

  If you don't mind squinting at unusably tiny text on a 15 inch laptop with a 4K display. (Reported as a bug, the response was "your laptop manufacturer needs to fix its firmware". Ugh).

      To be fair, I just read up on the bug and it was later re-opened and fixed by https://github.com/systemd/systemd/pull/8086; https://github.com/systemd/systemd/pull/8086; so I'll try sd-boot again some time.

You don't even need twitchy hardware. Ubuntu goes into an unescapable X server restart loop if you are out of space on the root partition when booting, and has no other obvious remedy than booting to rescue mode.
