Which is better?

[AzorpMeh]

Ok, i'm buying a new piece of armor, and my choices are:
Armor 50
Reduces damage from attacks
Armor (+10 vs. physical attacks)

OR

Armor 50
Armor (+20 vs. physical attacks)

Which should I pick...I'm a level 5 warrior/monk

The reduction is probably only a couple of points, so I'd say the second one would be better.

In the same situation I took the Ascalon Armor. It worked great. Appearently better than the higher armor level since some attacks can pierce armor, other cause elemental damage.
