Galen was Oneness amped tho.
"Driven by concern for his friends rather than himself, he embraced the Force completely, utterly, and was rewarded with a strength that made his efforts with the dark side look like those of a child."
Apart from that, a toying Sidious one-shotted Galen with Lightning, and shrugged off his Lightning. And in the DS scenario, which happens minutes after the canonical ending and thus there is no reason for abilities to change, Galen is curbstomped. Then again, Nihilus would be stomped by Sidious. But the same applies to Galen.
The quote you posted occurs after the Force lock when he sees Juno and the Rebels about to be gunned down.
Blasting back somebody with lightning hardly qualifies as a oneshot considering Sidious did the same to Yoda.
Sidious didn't no sell Galen's lightning since, as I showed on CV, it penetrated his Force defenses.
The DS ending isn't canon.

Nihilus, he has better showings, like draining an entire planet, and pulling his ship out of malachors gravity well.
Pulling ships out of Malachor isn't better then splitting a shielded ISD in half and it's debatable whether draining a planet equates with lasting against Sidious.

Wasn't Sidious toying with him though.
That's a possibility prior to the Force lock. In the Force lock itself though, Sidious was desperate and putting enough power into it to pierce through his own Force shields. Something Galen was not able to withstand but also walk forward against.
