Is season 3 a good adaptation?

I want to keep reading the light novel from where the anime ended in season 3, but only if the season is a good adaptation. I don't care if the anime changed a bit of the light novel as long it didn't made a great change, like Akame ga kill did.

I've read the first volume of the light novel about season 3, and already spotted the difference on how that bard girl were introduced, but I think that wasn't such a big change for me to read the rest of the volumes of the season.

So, do you guys think I should just continue reading the novel where the anime ended?
