Highest XP respawnable mob?

Quite a simple question: Which respawnable (i.e. non-boss) mob rewards the most XP on death per mob? Extra points for a list of all mobs in order.

So, it turns out that the Baby Zombies actually take the cake at 12 experience per mob (as of 1.11).

However, for standard spawnable mobs, it's a tie between the Blaze/Evoker/Guardian, at 10 experience per mob.

The only other suggestion to this is the Slime/Magma Cube. While each individual mob only drop a miniscule amount (4 for Large, 2 for Medium, and 1 for Small), if you consider the possibility that it has the chance to split into 4, then 4 again upon death, a Large Magma Cube/Slime can drop up to 28 experience.

Jockeys also drop an additional amount of experience, though technically not a single mob, and can drop additional experience, if the Jockey is carrying equipment (i.e. a weapon/tool/armour).
