While the anime and LN switches perspectives between Kumoko and the Hero, the manga stays with Kumoko. I kinda like the manga better because the time difference has never been explicitly stated. Kumoko's perspective starts when everyone is reincarnated, while the Hero's is 15 years later. The manga is basically following the timeline.

I think the Power of Friendship is working for both sides. The LN switches between Kumoko and the Hero after all. Plus the Hero's party only encounters serious threats when his opponents are related to Kumoko. The Nightmares, Wrath, and Sophia all have no problems against the HP. Yet Greed struggles against Sensei even after his powerup.
I’m so confused I jus came cuz I remembered finishing the anime liek 1 or 2 yrs ago and reading ts is confusing I can’t anymore
