Assuming you mean AP Ezreal as comparison:

Ahri: CC through Charm, Lifesteal passive helps you stay in lane. Still hits hard and can catch up on long distances with three dashes from her ultimate.

Ezreal: Wide AoE damage and global hard-hitting ultimate. Constant high mobility instead of one ultimate with three dashes.

Ezreal can also be played as an AD Carry and Hybrid, giving you more roles to play him as. You probably want to tell that you're playing AP as well, AD Ezreal is AFAIK the most common playstyle.

As for difficulty, I think Ahri is a lot easier to play, with lifesteal and 3 Fox-Fires prioritizing champions. Ezreal's Arcane Shift is both offensive and defensive, and go for one nearest target. Deals lots of damage as AP, but you can get yourself killed easily if used wrong.
