For the light side Id say Luke, his overall knowledge of both sides is probably as good as anyone and his views on allowing love and attachment would fit anakin well. And he is more than powerful enough to keep anakins attitude of I'm more powerful than u why should I listen to u in check.
For the dark side for pure effectiveness I'd say Bane. Bane is more of a cold blooded assassin get the job done type of teacher, vitate and palpatine more along the lines of a genius serial killer. Banes student would probably get the job done and get out while palpatines would try to savor their victory and get cut in half, or revel in torturing someone and end up getting thrown down a huge shaft.
