I like sorcerers for their casting flexibility, the way that once they've learnt a spell then it's almost always available to them when they need it. They get more spells/day than a wizard, and don't have to predict what they're going to need the same way. There are only a few levels where the number of really useful spells is more than the number a sorcerer can learn, so they don't suffer there.
I prefer wizards for their greater range of abilities. A sorcerer loaded up with fire damage spells against Firkraag? That's going to go well
A wizard can prepare specifically to face the types of enemies that will be around, and doesn't end up with only one or two useful spells. They can prepare the Mordy's Swords in a mind-flayer lair, halt undead for visits to Bodhi, etc. Their edge is most pronounced at low levels because the sorcerer really doesn't know a wide enough range of spells to be useful all the time.
And I'll also confess that I like to use characters that I'd be willing to play in a
PnP game (or have played in a
PnP game), and that means wizards over sorcerers every single time.
Back from the brink.
Like RPGs? Like Star Wars? Think combining the two would be fun? Read Darths and Droids, and discover the line "Jar Jar, you're a genius".
These, in the day when heaven was falling,
The hour when earth's foundations fled,
Followed their mercenary calling
And took their wages and are dead.
