Just pick which system's grub you want to use, and you can stop fiddling 
with efibootmgr.  Use grub2-mkconfig in your "primary" system to build a 
complete cfg file.

UEFI isn't complicating the issue at all.  Even if you had just one ESP, 
you'd still have two grub installations, and two files.  You'd still 
have to run grub2-mkconfig in the primary system.

And while it'd be fantastic if it weren't that way, it really can't be 
unless grub is "stable" in the sense that the configuration file syntax 
is finished, no new features will be added, grub2-mkconfig produces a 
predictable output, and all distributions run this stable version of grub.
