A few things that I didn't see listed above:
Wizards are likely to have more unused spell slots left at the end of the day. You will normally have prepared a few spells which you're not sure that you will need (such as a Silent Dispel Magic), but have every reason to believe could turn out to be essential.
Sorcerers have a much harder time qualifying for most PrCs, but when they do they get a much greater advantage out of it.
Wizards are better at crafting magical items. This is where spell selection and minimum level come in. A wizard can afford to get a spell that is only so they can make some particular magic item, the sorcerer is much more limited in what they can enchant.
