What is the easiest legitimate hand to get away from post-flop?

[Insistent_]

A non legitimate hand would be for example 444x or 4444 - trips/4 of a kind.

ASSUME OPPONENT HAS AAxx.

1. Before you know how the flop looks like (i.e. it is random) what is the easiest hand to get away from post-flop, that is what hand has the lowest expectation on a random flop against AAxx?

2. And two, the same question but which "okay hands" and better would be the easiest to get away from? Define this range yourself but define it pls.

Thanks!
