I do indeed work with many multiboot setups, and my experience with UEFI has 
all been positive.  Apart from the ease of applying changes in multiboot 
systems, I find that UEFI makes the boot process more open to the user, and 
accessible.  The only problems I've encountered appear to be caused by poor or 
limited support in old firmware, or by non-standard features added by vendors 
such as Apple.
