Whilst doesn't have the same concept as being kicked out of a Adventuring Party, the MC is instead simply fired from being the "Manager" of the Demon Army, also believing he himself is a Demon, but found out he's an incredibly powerful Human.
Basically same concept, but MC doesn't know their own self-worth, gets used throughout their time with said High Ranked Party, and then suddenly gets kicked out because they believe them to be useless, only to find out that said useless member was in fact holding their entire party together via logistics, amenities and pretty much daily chores.

Purely the similarities end with the suits, both show will showcase a set of BATTLE ARMOUR that requires transformation. Other than that, the shows are completely different in story, I recommend it because I enjoy both shows enough, and I really enjoy cool ARMOUR designs, and with these two shows having that, I'll recommend this regardless, try it out, Gatchaman is pretty fun to watch.
