1. Probably Illumi's needles. Aside from the fact that Illumi is way stronger than Shalnark, his needles can be thrown, and he can use many of them instead of being restricted to just one/two. Furthermore, Illumi can Manipulate his victim while doing something else as well, so he is not forced to hide when he uses his ability. He can even move dead corpses for a while, if I recall correctly (when he makes one of the Ten Mafia Dons speak).

2. Onscreen he waits too much, that is true, but remember when, after letting Leorio and Kurapika go, he became insane for a while and gave in to his killing frenzy? Plus, he is know to have murder scores of people. My guess is that even if he spares someone because he wants them to mature, he will go kill another person. The Last Mission movie is non-canon and has way too many flaws, if you ask me. On the other hand, I don't think he looked out of character when considering which of the Zoldycks to kill, since he wanted to make sure he had plenty of fun battles ahead.

3. Yes, although not so much as in the past.

4. It's possible, but I don't think so. At least three of their children were already born when he killed the PT member. Most likely he was hired by someone. Although the motto "We accept everything, so take nothing back" does seem to promise a vengeance (if he has "taken" Kikyo from the city).

5. Again, that's possible, and we have never seen him angered, so we don't know if the color of his eyes changes.

6. If they only use swords, I guess Nobunaga. He has a longer reach, and Iai focuses on speed, which would compensate for Feitan's quickness.
