Favored Soul is awesome, but you guys got it wrong.
Don't combo it with Paladin or Fighter, you already get the extra attack from favored soul. Doubling up on that ability is a waste.
If you want to make a Gish and you're looking at 5-6 pally or Fighter levels already, make it a storm Sorcerer.
The FS gives you armor, extra attack, and some free spells. (You get 2/3 from multiclassing Fighter or Paladin anyway). The storm gives you free spells and a slew of other abilities.
Storm doesn't give you free spells anymore as of SCAG.
I know it seems sub-optimal because you get armor and extra attack from pali anyway, but i think spiritual weapon is just that good. Its a bonus-action cast, no concentration required, every round repeating 1d8+cha. Obviously you have quicken spell, but if you are low on metamagic points, or want to conserve, spiritual weapon + eldritch blast or physical attacks makes you a powerful force with very low resource expenditure.
Look at the features for storm.
The fly thing is bonus action, so like spiritual weapon, it competes for that action slot. But I would rather have spiritual weapon.
Heart of the storm is decent damage, but requires you to start your turn within 10 feet of an enemy, and cast a thunder or lightning spell; there aren't many good ones.
Storm Guide is flavor
Storm's Fury requires you to get hit, takes your reaction so you can't cast shield, but it is quite a bit of damage.
Favored Soul gets you some really great spells at level 1, 3, 5, 7 and 9, and then a flight mode at 14.
I would say you can go either way but personally FS is more attractive to me.
