What is the difference between a Shell Bell and Leftovers?

Question

I really don't see the difference other than the Leftovers being better.

Leftovers restore 1/16 of your total HP. Shell Bell restores 1/8 of the damage you did.

So if you have a stall-ish Pokémon, it won't inflict much damage, so Leftovers' guaranteed healing is preferred. Guaranteed as in you would heal the same amount of HP each turn.

Answer 1

Shell Bell heals based off how much damage you do.(that means your Pokemon have to damage the foe and at the same turn it will heal you)

Leftovers heals 6% of your Pokemon health every turn.

Leftovers is generally considered the better item.

Unless you F.E.A.R.... then Shell Bell is the better troll item.
