G9II vs G85 with the 14-140mm Power OIS II

I had previously written off the G9II as being too expensive, but the current best buy sale for $1300 with the 12-60mm lens has me reconsidering.

My main camera is the GX85, and I have no interest in replacing it. However, I also have the G85, which I primarily use for video, or if I want to shoot with a larger telephoto lens (typically a heavy adapted vintage lens, not something M43 native). The grip on the G85 is far more comfortable for heavy lenses, and the video features are a nice bonus.

My favorite M43 native lens is the 14-140mm Power OIS II, it's just such a gem and great all-rounder. I like it equally well on the GX85 and G85. However, I've noticed it has a weakness for low light portraits, such as for a kids school production.

Excluding everything else that could be compared about the cameras, I'm wondering if the G9II offers any advantage in this specific situation, with the same 14-140mm lens. I'm guessing the answer is no since the sensor sizes are the same, but I'm curious what the real world results might be.
