If you are creating this blog as question thread instead. We got the forum for that: []

If it is not enough, there are also Discord and Reddit community around.

Anyway, the best answer to your question would be entirely depends on conditions. But there are few uber units which simply works in almost any kind of situations because the game intended for these uber rares to be the rare among rares. Prime example are uberfest units and their respective counterparts like Baby Gao & Shadow Gao, Mitama & Dark Mitama and so on the list.

There are even non-uber rare units but better than. Example like the Awakened Bahamut and Valk cat.
