I like 7, (though not as much as Oath/Origins), but didn't care for Celceta because it was more of the same with even less interesting characters/story and even easier difficulty. But most people loved Celceta so tastes seem to range on that one.
I'm sure 6 will be good, just heard a lot of "meh" about it 10 years ago so it sat in the rpg backlog. Now with this now Steamified polished version, I'll probably give it a run in the next month or two.
