First, prepared casters in general can change their entire spellcasting capability every single day, which is an insanely strong capability by itself. And in case of Wizards they can choose from 44 spells at the very least from their level-up, not even mentioning Clerics and Druids. A single Wizard can function as almost 3 entirely different character on a daily basis, even with my proposed rule patch. That's strong enough, even post-(supposed)-nerf.I'm not sure what you are saying. Are you trying to say a wizard should be able to have less spells prepared each day and a sorcerer should have more? There would be no reason to take a wizard than, ever.
Second, as a contrary to the first point, the Sorcerer especially has an absurdly small number of spells known (15 max, seriously? Even the Bard has a whopping 22). As metamagic is no longer the godly presence it was in 3.XE, it would never make up for this impossible design decision; seriously, does someone in the 5E dev team decide to benchmark Skip Williams with his supposed hatred of Sorcerers? Actually, I find it painful that one early Unearthed Arcana (Favored Soul) almost fixed this by trying to give them at least low level (1~5th, 2 per spell level) fixed spells, then mess it up by ditching it in the final version in SCAG (as far as I know of the book).
