rEFInd is VERY good at dealing with multiboot environments as it scans all kernels/OS/bootloaders on boot so it will autodetect everything without any mainteneance on your side.
It also allows you to edit the command line parameters (actually allows you to set up multiple sets of them in a config textfile beforehand so you can just choose another profile if you don't want to type).
It also has menu for EFI tools like memtest and EFI shell (that you need to provide and drop in the appropriate folder), and can reboot to UEFI firmware (as long as the UEFI allows this at all).
It also detects automatically the secure boot management tool things a distro installs in the EFI partition so you can also invoke them on boot to do key management.
GRUB can do all this only with extensive configuration that has to be updated manually on any kernel/OS/bootloader change.
What GRUB can do which rEFInd can't do is actually access LVM or RAID (* with metadata=0.9 it can access it but your array size is now limited to 2TB) or encrypted partitions to boot your kernel.
