I'm a bit unclear on why you suggest that scroll scribing benefits the Wizard more? In 2024, all that's needed is you have the spell prepared, arcana or cartographer tool proficiency and the gold/time to create the scroll. Wizards don't do this cheaper or faster anymore.
Its related to how the two classes prepare spells. Wizards can rearrange their prepared spell list every short rest. Sorcerers need to wait for a level up. This lets the wizard prepare a spell, scribe it, then swap out the spell for a new one to scribe. This gives the wizard a larger pool of niche spells on demand than the sorcerer, who tends to not pick up said niche spells.
I know they're not called known vs prepared casters anymore, but the rules for scribing scrolls absolutely benefits prepared casters more than known ones.
EDIT: Side note on scrolls: Can't a Sorcerer with quicken use the magic action on a spell scroll and then cast a leveled spell with his bonus action from quicken? It's not clear to me whether this interaction works or not.
EDIT2: On further research is appears this does not work due to quicken metamagic restriction of you casting more than 1 leveled spell, coupled with scrolls technically working by you casting the spell from the scroll.
Yeah, sadly, magic items can't adopt anything like that. Base caster options only - even your proficency bonus is set to the lowest level possible to cast the spell.
Only when your only metric is spellslots per day.
Sorcerers get Sorcery Points, Innate Sorcery and if my suggestion was followed then the ability to give out PB Heroic Inspirations per short rest from the Musician Feat. I think if you factor in all resources that sorcerers are just as much, if not moreso marathon runners, the primary difference is that they can also sprint faster.
Well, yeah, I'm bringing up spellslots per day, because that's an advantage of the Wizard to compare to the Sorcerer's metamagic and innate sorcery. Both marathon running and sprinting are Olympic sports. One is not better than the other; however, they are very different skill sets. One is all about the burst, and the second is about how long you can last.
If we had, say..... fireball casting as a fantasy-Olympic sport, then Sorcery Points, Innate Sorcery, and Metamagics mean that every individual fireball the sorcerer casts? Its almost always going to be better than the equivalent cast by the wizard. Bigger boom. However, wizards will end up casting more fireballs per day than the sorcerer, even though the sorcerer's individual fireballs are consistently better.
Thus, Nova vs Sustain.
Your conclusion was "battle vs exploration" which I don't think is correct. Its a quantity vs quality question in battle, and then "exploration vs social" out of battle.
I assume this must be a reference to the level 5 spell memorization feature.
A bit of that, a bit of just being able to swap out their spell lists daily, a bit of magic item options. Swapping spells out to prep for an encounter is an advantage of the wizard.
The thing is Wizards don't typically have that many known spells outside their prepared and most of those are likely going to rituals.
34 at minimum, which is 2 more than Sorcerers at their best, with the option to get more.
And not always rituals. They'll also be a fair number of spells chosen specifically to be kept to the side, then prepared for when the specific situations they're meant for come up.
