That's a tough call because it is only at longinus level due to Gaspar's insane vampire ability. His SG "Forbidden Balor View" is awesome, but it hasn't acheived BB and it is Gaspar's power that animnates the incarnation of Balor (maybe... not really sure if Ishibumi said exactly that). Upon Gaspar's death, it would migrate to another host and never attain that power level. With Draig and Albion, the Longinus level power and abilities are part of the package, only needing to be unlocked.
