When I played in NA, I used mostly archery. I would say ranged is best, but I do not like crossbows so I stick to archery.
At least for me, manual blocking becomes much harder, for shields the reply time is too short (unless you start spamming left swing, which I beliee to be lame), and in general melee is faster than ranged. Also, avoid getting in duels, try to go for the group.
