You need a higher level of defence to wear barrows. Therefore, I think Barrows is better.
They Protect you hand, the only better gloves are rune, dragon, and Barrows
Most of the Barrows sets give better defence bonuses, and roughly the same strength bonuses, depending on your weapon, but since Barrows items degrade over time (Totalling 330,000 which can get rather pricy.)
Torags makes Dragon almost Obsolete in terms of defence. The down side is tha Torags is Barrows, meaning it degrades.
you have to get a ring of wealth 30kish =p
anything rune, dragon, barrows, godswords ect.... id go rune schimmy for cheap, whip for expensive, or dragon skimmy for mid range
you play the minigame barrows

from worst to best - bronze, iron, steel, black and white, mithril (mith), addamant (addy), rune and dragon (drag). there is one more level of armour above dragon which is called barrows. there are 6 different sets of barrows armor and each ahs a speacial effect when wearing the whole of that set (helmet, body, legs and weapon).
Barrows equipment is only obtained from the chest that you can open upon the completion of the Barrows activity. You will not receive Barrows equipment as a drop when you kill the Barrows Brothers.
Dharoks legs have better defence bonuses but they degrade like other barrows, dragon legs are slightly worse defence. However, dragon legs are at a low now (only like 600k) so this would be the time to buy and even if you don't want them forever, sell them once the price rises again. Get good use out of them for the time being and once they are 800k+, sell if you don't like...Merching is good $ as well. Gl.
I don't know what the best armor is. The most expensive would be a full third age set. My favorite is a full dragon with dragon full helm, dragon boots, worn-out dragon gauntlets, oynox ring and neacklace or on of the full barrows sets. I really don't think there is a "best".
