What's best for 2 finger typing between QWERTY, AZERTY, and QWERTZ?

I know none of these are particularly good for any number of fingers. I normally do use better custom layouts, but my new phone only has QWERTY, AZERTY, and QWERTZ as options. Installing an app for a different keyboard layout is not an option. Do people who use these on their phones have any input as to which, if any, is best?
