They have less power density than other lithium-ion chemistries when both are new, but the dropoff over time is also less. That means that unless you replace your power banks fairly often, the LiFePO₄ version is likely to have higher density for much of its lifetime. They also tolerate at least double the number of charging cycles.

Not sure how to go about marketing that in our current disposable society, though.
