After playing Wizard, Sorcerer is pretty miserable. Sorcery Points are too few, and there's just levels when they don't get any new spells, while Wizards are always getting at least two, and can copy a lot more. Known spells just seem like worse than prepared spells in every way as well.
I have a very different relationship with my wizards and sorcerers.
It is always a struggle to pick sorcerer spells, but at the end of the day I rarely feel like I do not have a good option to cast, and even for the sorcerer I end up with spells that do not even get cast once during a level. Honestly, the pinch I feel in available spells for wizards and sorcerers is usually about the same because what I wish I had at a given time that I do not have is usually so conditional that wizard had no more room for it than the sorcerer did. To that end, it is the capability of the metamagic to 'supercharge' spells that really sets the Sorcerer apart.
With the inclusion of the Aberrant Mind and Clockwork sorcerers, there are sorcerer options that end up knowing far more spells than a similar leveled wizard will have prepared. Only certain clerics (and land druids) have more spells available to cast.
I know that wizards get rituals for more flexibility ... but sorcerers get 1 (or 2) more cantrips.
When the sorcerer can counterspell from over 100 feet away, or give disadvantage to that one spell that has to get through... it just makes the sorcerer so much more effective.
