Just curious which people prefer, and if either ends up being significantly better than the other by the end of the game.

I currently have a warrior in heavy armor and he seems to be indestructible at level 25.

heavy armour is better for anyone who going to go head long into a fight. Light armour is there more as a backup for sneaky types in my opinion

I wanted to wear light armour, but everything after leather looks horrible so I switched to heavy armour.

Haha light armor looks like heavy armor in this game.

With all equivalent perks, Light Armor provides you with 3/4 the armor rating that heavy armor does, so heavy armor is better for protection over all. Light armor, gives you a perk for +50% stamina regeneration though, which is very nice for keeping those shield bashes going. Over all, I would say that Heavy Armor is better for 2 handed warriors who wont have the protection of a shield, but Light is better for stealth and shield warriors.
