I would go with something that the player finds cool for the PC. I like the idea of donning armor since it is cool and never comes up in my game anyways. You make the PC wait until you get the armor to the city, or to a magic place in the dungeon to actually give the reward. I tend to not give out +1 plate armor, but would give it something like advantage on saves from dragon breath or 1/day turn a critical to normal hit.
