This seems odd to me. Preparation is straight up superior to known spells, there's no subtle balancing between them. There was in 3e, when you had to prepare spells in slots ahead of time. But in 5e, preparation is "You just long rested, here's your list (or spell book), pick level+Mod of them." Known spells is "You leveled, pick one new spell and swap an old spell for a new spell. You know level + 1 (or level+3 if you're a bard). As a juicy new bonus, you can now swap one spell for another after a long rest."Now, I am not just picking on Sorcerers et. al on this. Clerics, Druids, and Paladins are even worse offenders when it comes to versatility. They already have access to their entire spell list, but by at least balancing that out with selecting prepared spells--it means they can easily find themselves in a situation where they don't have the proper spell prepared.
I feel like the real odd duck after these changes is wizard; they're now the only caster class that can't access their entire spell list after a long rest.
