Need help with Esper distribution

[Nezkeys]

I just unlocked the first esper Belial but it doesnt really tell me what it gives me so i dont wanna screw anything up. First of all I just need help on who to give belias too. I think im gonna need help distributing them all if there is no info on what they provide. Here is the party ive chosen to go with if it helps....

Vaan - Shikari/Foebreaker
Penelo - White/Time
Ashe - Black/Monk
Basch - Knight/Bushi
Fran - Archer/Red
Balthier - Machinist/Uhlan

I may change to this btw so keeping a second save file...so would need a different distribution for this one i would imagine...

Shikari/Time (just for something to do with the mp lol)
White/Foebreaker (this swap also eases pressure on the white mage and turns me into a paladin of sorts i guess...that use axes and hammers lol)
Black/Monk
Knight/Bushi
Archer/Red
Machinist/Uhlan

I have that spreadsheet from google docs so gonna take a wild stab at guessing the best ones based on my party if i understand this correctly. here goes....

Belias - Basch (for the item lore lol)

Mateus - Basch (curaga/regen/cleanse/esuna)

Zalera - Vaan (435 hp) or Penelo (ether lore x3). i could give it to basch bushi gets blood sword but since i have bushi paired with knight i assmed this is a waste since knight already gets blood sword?

Adrammalech - Vaan (shades of black/1 battle lore)

Shemhazai - Fran (heavy armour 10-12, cleanse, esuna)

Hashmal - Bash (Faith Bravery Curaja)

Chuchulain - Vaan (protectga/shellga) or Fran (firaga blizzaga thundaga sleepga)

Zeromus - Penelo (270hp Addle Shear)

Exodus - Basch (850hp)

Famfrit - Balthier (Hastega/Slowga/Reflectga/Vanishga/Graviga/Warp/Battle lore) or Ashe (Arise, Dispelga, 730hp)

Chaos - Ashe (Holy, Protectga, Shellga, Esunaga)

Ultima - apparently blm/monk gets 3 swiftness without esper so no point giving it to ashe for just telekinesis. here are the other options. Balthier (expose, 3 magick lores), Basch (battle lore, telekinesis, stamp), Vaan (phoenix lore x2), Fran (claymore, defender, save the queen). im thinking just give the mch/uhlan a break or give rdm/archer ability to equip those greatswords for some decent melee damage on trash?

Zodiark - Basch (Excalipur, 390hp, Heavy Armour 9-11)
