It looks to me like the Ideal Tan Twister wire nut by hand provided the best connection. If I'm only putting 2 or 3 14's or 12's together, I use the tans by hand, but if I have more than 3 wires I use my Kliens to make a good twist. Also if I'm making up lots of boxes or cans, I use the tans with a drill driver for speed. I've checked the connections and they are as good as it gets.
