Shaka is a Killer wannabe. I appreciate the effort and put him in #1.
Lilith and York are fighting for the best woman design, but honestly Lilith beats York in every single department. She comes 2#.
Edison and Pythagoras are contending for the best robot and imo Edison is so funny I'm giving him #3.
Atlas is pretty unique in that bunch but doesn't hit me...
Shaka, Lilith, Edison top 3 (following the numerical order, ironically) then come York/Pithagoras and finally Atlas.
