If you have heard good things about the paladin story quest, you may have been deceived. The gladiator class quests are okay, but the 30-50 and 50-60 paladin quests are probably the worst in the game. The level 60-70 are about the same quality as the gladiator quests.

Marauder is okay, while warrior from 30-60 is not my favorite. The 60-70 quests are better, but they take a turn that may not be to everyone's taste.

Dark knight is probably the most popular, especially the 30-50 and the 80 quests. I also think they are quite good.

Gunbreaker isn't bad. It mostly serves as a way to provide backstory to the Hrothgar and Bozja.

Lancer was also pretty decent, though maybe nothing groundbreaking. I know people like the dragoon quests, but they never really got interesting to me until the 60-70 quests.

Pugilist is also decent, though the level 30-50 monk quests were kind of boring. I personally believe they got better from 50-70.

Samurai is pretty good from start to finish, but 50-60 is really good.

Rogue is great; same writer as the dark knight quests. Ninja quests from 30-70 aren't bad, but not outstanding. They aren't as great as the rogue quests, and kind the same story beats.

For some reason, I could not follow the archer and bard quests. I want to say the 50-70 bard quests aren't terrible, but I simply couldn't follow along.

Machinist is great. You spend a lot of time shooting people in the kneecaps.

Dancer was fine. Interesting, and has some good music, but I didn't stand out much to me.

Thaumaturge and black mage were fine up to 50, but 50-70 was kinda forgettable. Supporting characters were good, but the plots felt bland.

Red mage is overall great.

Arcanist was pretty good. Summoner was boring IMO, but scholar is fantastic.

I liked the conjurer quests, though a lot don't. White mage gets a little better in the 50-60 and 60-70 quests, but the 30-50 is eh.

Astrologian is also really good.
