It's a difficult choice, because there's no best option - just whatever clicks with you. Stuff like hammer, greatsword and longsword are relatively uncomplicated mechanically and force you to fight deliberately. Do sword and board if you want a little more mobility. It's all really a matter of fucking around and seeing what items clicks before you start to get too invested in one particular branch.

charge blade but only if you hate yourself

I haven't played the most recent couple of games, but from what I recall, hammer is very straightforward.
