Both involve humanity having shifted from a dying Earth, to live seemingly ideal lives in space. Both involve strained relations between people living freely on Earth and those in a strictly controlled utopia in space. Both involve confident protagonists who visit Earth and later try to change the way things work, back in space.
Both also use similar styles in animation and character rendering.
Both also have fairly simple plots that don't require a lot of thinking to get into.
The main difference is that, while Freedom's sci-fi elements are largely grounded in reality, Expelled from Paradise goes full-on sci-fi, complete with mech battles and sentient AIs.
