DA or SK: i asume you consider oly only, so SK wins due sharpened skills and a lot of options while DA falls short on panther support skills. In a tank v tank fight a good TK would win in my option 80% of time. TK is more self-sufficient while SK has more controll, but both haw good counters to mele and magic skill users alike.
Mass PVP: fastest tank TK for small groups, best hp/ aoe control - paladin; Both haw Touch of Life.
