So... as someone who ran away screaming when AoS came out, but is now increasingly intrigued by the new models (sky dwarves! sea elves! murder elves!), how much fun is it as a game? Is it worth getting into, or should I just stick with 40k?

I'm particularly interested in how much AoS is just 'throw dice at each other', as it seems on first glance as if it would be worse than 40k, what with the static to wound roll as well as static to hit roll, it seems like there is always going to be a clear 'best' unit, rather than having to weigh up whether I want to have high toughness, good armour, high strength, good ap etc.
