I notice that the LM339LM339 quad comparator comes in 2 different varietys: general-purpose and differential. Besides a big difference in price, what is the difference between the two?

Specifically, I want to use it in a slow-changing (as in whole minutes before crossings) single-supply (12v) circuit that needs to output very close to 0 for Vsat-.
