100% tpback. Bed nuker is pretty bad too. Well flight is probably the worst but I've only ever seen one flight hacker.
Reach is hard but if you have a height and gear (sword) advantage it's not too much of a problem.
AntiKB, most of the time makes it easier to kill the hacker with fireballs/tnt, or just critting them out.
Autoclickers are pretty useless unless the hacker is actually decent at the game.
Bhop makes it pretty hard to win a 1v1, but you don't want to 1v1 hackers anyway so it doesn't make too much of a difference.
Killaura/forcefield is pretty hard, but can be countered the same way as reach.
Scaffold is annoying to fight if they use it well, but usually they just flat god/breezily to you, which isn't that bad.
EDIT: Nevermind I forgot about the most op hack: autorespawn
