Sorcerer.... Well, sucks? lets see
The Shadow Sorcerer level 7 can Twin Polymorph into 2 Giant Ape. For ****ing powerful beats that deals
+9 to hit, 3d10+6 x 4 with 150 HP.
As bonus action The Shadow Sorcerer uses Hound of III Omem that is a buffed Dire Wolf with Pack Taticks for free advantage, If the Hound hits,
DC 13 or knock prone (OMG, Knock Prone against 3 ****ing powerful beast is a death sentense).
The best part is... The Hound apply disadvantage against all Sorcerer's Spells.
The Hound combo with Giant Apes and still apply disadvantage... It's insane...
Are you trying hide? The hound know your location.
The Sorcerer can deal 100 damage per turn (If all hits, HIGH CHANCE) + Sorcerer spells (With Disadvantage)...
It's long duration combo that is insane.
If the Sorcerer wants to spend more resources, the sorcerer can
summon multiple hounds for still more insanity.
The Sneaky Mage.
The V. Human Shadow Sorcerer level 7 with Prodigy feat (Stealth expertise) and Ritual Caster for Find Familiar.
So, It's +10 Stealth Check + Familiar' help action for advantage.
Now the can cast spells against enemies with IMPUNITY. Yes, It's the power of SUBTLE SPELL.
The Hound of III Omem and Careful Fear or Hypnotic Pattern is too insane and your party will love you... It's literally a game changer, both spells is save or die.
With Sorcerer's
FLEXIBLE CASTING, the sorcerer can spend all level 3 or lower spells slots into Sorcery points, then, Sorcery Points into higher level spells slots.
So, at level 7, the Sorcerer can cast Twin Polymoph
3x/DAY... Look. 3x day against once/day Wizard.
The Sorcerer 2 giant ape for 3 hours/day x Wizard 1 giant ape for 1 hour/day...
It isn't fair.
Moon Druid: "I'm a joke to you?"
The Divine Soul Sorcerer
With flexible casting, creating more 4th level spell slot, the DSS Controls 24 Undeads with Animate Dead (Against wizard at maximum 12) for 24 hours and still casts twinned Polymorph for 2 Giant Ape for 1 hour.

Or just quicken empowered elemental afinity fireball that deals 40 avg damage
action for Empowered elemental afinity Fire bolt for 19 avg damage
