HNM - Genie is better. Or this with ES. Otherwise you will see a big negative difference.
Puddings - Morgana is better, but not when the weather or day supersedes the element you're casting. (Eg. Thunder/Burst was resisted very frequently during Earth weather).
So for 500k, I think it's worth it if you're a number *** like me, otherwise, it's not a full time piece in any situation.
On BLM the -8 MagicACC shows itself alot more than the +8 MAB.
Regarding SCH this is a worth while body piece, especially if you like nuking puddings! They can control the weather around them and ehance their own MagicACC.
Not worth the pain and not worth the price. Should only be used stacking with EleSeal which mean for the most part unless you have merited it its only going to be useful ever 10minutes I would say save your gil you can stack MA without losing the MA in plenty of other places
I think everyone can agree that a SCH has a floored resist rate puddings without needing to stack skill/m.acc gear or control the weather. Even RDM can nuke without much adding much skill.
The difference between SCH and BLM elemental skill is 20.
20 skill ~= 20 m.acc
Therefore BLM can wear this and still nuke on puddings and still have more m.acc than a SCH (before weather effects)
Therefore, this is the best meriting body for BLM, other than Morrigan's robe.
