You don't really need either, unless you want to ride at the TOP of the
atmosphere. If you were willing to sink a few dozen kilometers into the
atmosphere, it would quickly get so dense that you would have to design
some kind of bathysphere (aerosphere?) to resist the pressure. Then you
would just have to maintain a normal pressure inside to be bouyant.
Then again, by the time the weight of the displaced air was close that of
your bathysphere, we're talking holding out some SERIOUS pressure. It
looks like you'd want a diamondoid sheath in order to be practical at all.
