demon's soul class help

i was looking at the different class types for demon's soul and i have narrowed it down to 3 different choices which are thief, wanderer, and royal so out of those 3 which would you guys reccomend.

well royals are way too easy in my opinion as they're way over powered, but the theif is a good challenge as u have to roll and attack little. i would do thief

^ as if you need more of a challenge from Demon's Souls. :P

Thief

Wanderer

Royal
