To be honest, while SMN has more buttons to hit than BLM, I find all those abilities, pet management, aethertrail management, and the like to be a lot less annoying than juggling an Enochian timer just to cast your highest tier fire / ice spells which didn't require such ridiculous upkeep pre-Heavensward. To sum up the two jobs, I think Summoner got a lot better while Black Mage just got annoying.
