In my book, the ability to decide on the fly whether a couple fireballs or a couple dispel magics are needed, the ability to cast that dispel magic silent when you are silenced, but normal if not, the ability to cast any one spell among your spells known as often as you have slots free is tactical flexibility.
IMO, the ability to choose from a great range of spells when preparing is strategic flexibility, the ability to cast on the fly is tactical flexibility.
I have yet to see the mage who, without some rod of metamagic, can throw 4 to 5 silent dispel magics in a round, or 4 to 5 silent still dispel magics when needed.
My bard can blow all her slots on healing when needed, or on buffs, or beef up her performance after a day without battle. My sorcerer can cast dispel magic until it works, or cast fireball as long as foes vulnerable to it are on the battlefield, or cast a couple wall of force.
That is flexibility for me, the ability to spend your slots as the situation demands it, even going to the extreme of using up all your slots for magic missile if that is the only thing that works, and the situation demands it.
All I can say here is that I have NO idea what all that still, silent 4 to 5 times a round stuff you're talking about means. Sorcerers use metamagic feats like everyone else, only it takes a full round. But maybe that's not what you're referring to, I just can't tell.
You're welcome to your definition of flexibility. I'm just pointing out that sorcerers get very few spells known, and if your spells known are no good in situation X, then you're no good.
