Not sure we're going to see eye to eye on this one.
To me metamagic is nice, but it's not Spells Known * 1.5, especially because you only get 2 metamagic options from 3rd to 10th level (which is is the zone most games die).
Most metamagic are great, but they are usually limited to a couple of spells known per option. Quicken is really the only one that is pretty much always useful. And Sorcery points never keep up with daily needs for my experience. I'm always burning through them at a prodigious rate. Then I have to decide if I want to just not have metamagic the rest of the day or burn spell slots to get some back. Unlike a wizard who can get back 1/2 their burned slots 1/Long Rest. That is so many sorcery points worth of casting ability that they just get back.
Yes, a sorcerer has more cantrips. But all the sorcerer has without being really creative or multiclassing, etc is spells. Bard's have a bunch a bunch of other things going on on top of knowing more spells than a sorcerer. The Warlock also has a bunch of other options depending on which Patron/Pact Boon they choose + Invocations.
My point is that by keeping them to the least spells known of any of the Charisma classes, they are overly narrow in their options. Not only do Bards and Warlocks KNOW more spells, they also have more things they can do besides just spells with all their other class features and options.
A sorcerer basically casts spells. So they should have more spells known and flexibility than the other Charisma-based caster options. Not near a Wizard's level obviously as that is the thing. But Sorcerer's are inadequate IMO in their spells known.
Now I know your full of it. You just lost credibility. Warlocks suck as a caster. That you are even trying to compare a sorcerers casting to a warlocks tells me all I need to know.
