I wouldn't count exploiting a bug to get infinite Sorcery Points as a valid argument to be honest.

After my 2nd playthrough I'd say that there are circumstances where a Wizard is relatively close to a Sorcerer, but the explanation is a bit spoilery.



One of the big strengths of a Sorcerer is being able to Quicken their spells to turn a bonus action into a 2nd spell cast (which BTW does not work like this is in PnP, but whatever).

If you get your Wizard the 'awakened' Buff from the Creche that allows you to use Illithid powers than that takes part of the gap due to Quicken away, since now the Wizard has very impactful options for the bonus action. Perilous Stakes is huge.

I believe Heightened and Twinned Spell still makes the Sorcerer better (especially Heightened, which is also not correctly implemented). But it narrows the gap a bit.
