As opposed Scale Mail Armour +1?

Chain Shirt weighs 10 kg less, so it does not require 10 Strength to use, has 1 less AC, and does not give Disadvantage on Stealth.

So does anyone use the Chain Shirt at all? After all, stealth in this game is simply not that useful, the weight difference is negligible considering we can carry so much weight, and +1 AC is just safer.
