Personally, I feel like pages require the most patience. No party skills means that you have to make some friends or train solo for about 40 levels. I like fighters, but if you're pretty funded, you don't really need rage. For third jobs, I feel like Crusaders have more options while White Knights' trainings are dependent of which element they mastered first. When you finally get to 4th job, that's when Paladins really begin to shine, although they are not as good for bossing as Heroes. Just my 2-cents on the classes.
