LU: just a tidbit that you might appreciate. In your quest to find the more important aspect, Hashkafa vs. personality, realize that IMHO Hashkafa usually shapes one’s personality. So it’s really not an either or, but their Hashkafos (if honestly portrayed) will give you clues to their personality.
A lot of it stems from working on one’s middos based on what he/she deems important. Again, honesty is key here.
