Best armour hasn't changed much aside from the fact that it doesn't give offensive bonuses. You can always search any item in the G.E. and see what armour/life bonuses it gives you.
Melee wise, i believe torva is still the best going by defence bonus and hp bonus. I did notice that bandos boots are now better than dragon. I'd say the new armors that I'm expecting to be released next week will be the best or atleast equal to torva.
