Kim is right. There is no way the xp is different. All spells (LT aside) give xp based on a formula. The only variables are XP mod, spell level, and spell power.
LTs are a bit different but the same spell in multiple guilds functions exactly the same. Just like haste for an AM, NB, SM all have the same dev cost, duration and mp cost (and casting skill for that matter).
