Do the old Sorcerer subclasses really have better features?

At lvl 10, where Aberrant can get Synaptic Static in his list, he becomes a really mean blaster. Damage wise Dragon has the potential to do more, but I think Synaptic Statics and EBTs are more impactful spells and have better damage types (and of course the very valuable INT save). Considering that Aberrant can downcast them through converting slots, he is going to have a lot of firepower.

For a comparison, at lvl 10, Draconic will have 3 fireballs, 3 walls of fire and 2 synaptic statics.
Aberrant will have 9 synaptic statics or 11 evards autosubtled with his lvl 3-4-5 slots.

Through these 2 spells, you can cast one synaptic static and one evard's per combat for 5 encounters, which would probably take care of the adventuring day by themselves, and you still have autosubtled suggestions, telepathy and high cha for out of combat. This is a lot of control and the damage is more than fair. And all these in addition to the filthy cheap and twinnable Tasha's Hideous Laughter and Dissonant Whispers that he can use pretty much at will past lvl 6.
