Is Atou an A tier advisor in Isekai?

Havent watched Overlord...so cant say anything about Albedo.... But regarding tensura, both Oni were from that world, and Rimuru was isekaied, meaning technically Oni were advising to best of their knowledge in their world. Atou got transferred to Mynoghra (I think) along with Takuto, so personified best ingame vice-commander and the ruler both found themselves in their area of expertise. So its hard to just put Atou over the Oni from tensura. At least if you ask me. Besides, Atou "has lived through" previous gameplays, so she would have more knowledge than inexperienced Oni who were assigned advisor roles by Rimuru

I’d say Atou and Albedo are better advisors, and have the advantage of preexisting knowledge and high ranking.

Atou remembers all the gameplay her and Takuto have been through as well as being the highest ranked nation on the leaderboard of a strategy game.

Albedo is the advisor one of the strongest guilds in Yggdrasil, an extremely popular game too.

I’d probably say Atou, but just slightly, given the context behind the each series. Though there could be the argument that Atou was carried by Takuto and that Albedo is better.

I’d say Albedo cooperates and trusts Ainz/Momonga more, but way too much that it backfires. Due to this, Atou wins in this regard.

Atou trusts and cooperates with Takuto very well, however, she is always willing to criticize and speak negatively of Takuto’s actions.

Albedo has a lot more faith in Ainz, but that’s the issue. Floor Guardians and other NPCs are too trusting of Ainz because he is a Supreme One. They view Ainz as a perfect being who cannot make mistakes in a sense. To them, to doubt Ainz would be a sin, so they believe that there’s always a bigger plan that they don’t see and that he thinks several steps ahead, even when he doesn’t.

Atou doesn’t look at Takuto in this regard and is willing to criticize him, whereas Albedo won’t and will go along with nearly anything Ainz says.
