KoW vs AoS vs The 9th Age

Exactly one year ago today the world of Fantasy Wargaming changed significantly. One of the oldest and most popular games, Warhammer Fantasy Battle, was ended by Games Workshop and replaced with a new game called Age of Sigmar. Naturally, lots of players and hobbyists were unhappy and some even went to extreme lengths to show their displeasure. One year on, I feel that this is a golden era for Fantasy Wargaming.
