These days that depends on the type of ticket you buy, as well as how many miles you fly per year. You also need to factor in where you live. There is no single answer.
If you're a leisure flyer, AA may be the best fit as they offer 100% flight miles plus bonus miles at the various elite levels. Alaska, which has a lot of partners, would also be worth looking at.
If you're a business traveler buying high-priced tickets, any of the carriers you mentioned might work for you. United and Delta award miles based on the price of the ticket, very different than what AA does.
