I don't really have a favourite build, now days I run around at level 1 most of the time, the game is just too easy if I don't hold back :/
Claymore is more of a quality weapon, I prefer to go all in with my strength builds and use Demon's Great Machete / Axe, they have tons of durability so you can turn them into crystal and use Power Within for ridiculously massive damage / stun lock. For a strength/int build you should give Man Serpent Greatsword a try, it has much better strength scaling than Claymore, pickaxe is another great choice for buff spells because of its fast attack speed and Leo Ring bonus.
For dex build I personally prefer Balder Side Sword over katana, the strong poking attack is incredibly powerful (more powerful than katana), it's unstoppable when used with Leo Ring and Power Within.
