Not even close. Finishing fates at least yields you something, however miniscule the gil and seals rewards are. Additionally, you can level up your chocobo or queue for duty while doing atma while you can't even go get a drink for fear of missing out on a fate that will most likely be zerged down in 30 seconds. Its also not 1 fate, but 27 in total in addition to killing 900 mobs, 27 dungeons and 300 brayflox runs. Maybe you like to stand around doing nothing, but I like to keep myself active and doing mindless fates beats staring at your screen for hours never knowing when its going to spawn. I'll take atma any day.
