For me, easiest to hardest:

Ancient Egypt - Such weak zombies. The only real threats are the Pharaoh Zombie, Mummy Gargantuar, and Zombot Sphinx-inator.

Pirate Seas - Spring Bean, Spikerock, and Snapdragon make everything easy.

Dark Ages - The only hard levels so far were Levels 9 and 10.

Wild West - The zombies have such unique qualities that make everything hard.

Far Future - Such high Hp, shield zombies are annoying.
