I can't add anything to the responses that you have already had except my own preference which only echoes many, the YG Escher. It is my most consistent and never fails.

Note that it is more the hand than the hone. The best finisher is useless in the hands of he who does not know how to use it, or it will improve an edge very little otherwise. Unless your edge is shave ready off an 8K, it will contribute nothing.
