So far Anime is winning.

I am on volume 07 chapter 6, the tournaments solo battles have just concluded.

There has been very minor new details, mostly it feels like bits the anime didn’t manage to fit dialogue for. (E.g. that only those over 90 can’t use their normal gear in the tournament, princess lily's actual intentions, Lutos previous partners, Forest Ogres using tree execution on Makato during the long hand holding. (Don’t tell Mio))

There’s been no major changes or revelations.

But I have been enjoying it. I would say it’s been worth it for the extra tidbits.
