Evade?

Could someone explain Evade to me? Is a high or low Evade on your Status screen better? What about in the item descriptions on this site?

Thanks! :)

Evade
Evade determines whether an enemy will hit you or not. Also, it can
actually determine how many times an enemy hits you. If an enemy is capable of
hitting your 4 times at once, if you have a high Evade stat, he might only hit
you twice, once, or maybe not at all. Each character has an Evade value equal
to his Agility plus 48*. Your Evade value equals your characters basic Evade
value MINUS all the Evade values of your armors put together. So, heavy Armor
like Iron Armor and Steel Armor have a high Evade value which is bad.
