That Eternity/Entropy sequence with Insane Genis is often hyper-exaggerated... So if that's what you're referring to, I agree. 👆
Canonically, Photon Genis > Insane Genis... And the former's stalemate with Sentry(pre-Siege-'awakening'😉 gives us a decent means of gauging the power of his previous/inferior incarnation, imo.
ie. Photon Genis ~ Sentry(pre-Siege-'awakening'😉 > Insane Genis. 👆
The pen is mightier than the concept. Orion in a box 📦. See how using their lows to prove a point becomes skewed? Although with She Hulks performance isn’t as far off base as you think, she’s stronger by a decent percentage than Hercules these days. She can tap into crazy amounts of power and challenge Thor, even put him or her on their backs as seen with Jane.
Genis may not win, but the idea of Orion outright overpowering him isn’t going to happen. I’ve heard worse though, like Black Adam manhandling Immortal Thor, and giving Galactus the work over so at least this isn’t nearly as skewed.
