Seriously, this is more of an opinion, but I say to bring the best stat raising armour, because if you have prayer on, you will not be hit.
The best armour to wear depends on the combat style you're using. If using melee, Dragon armour is the best, Black dragonhide armour is the best for ranged, and Grifolic armour is the best for magic. Using the wrong style armour for the wrong class will lower your accuracy.
Body armour, helmet, greaves and sandals.
Granite if you have over 1mill.
The best armour for a Warrior is Plate. You can only wear plate from Level 40 onwards, until then wear Mail.
i guess full red dragonhide
It depends on your preference, I prefer to be able to dodge fast so I wear light armour, if you don't like dodging then use a shield with 100% physical defence and heavy armour.
The best armour for an Acrobat would be light armour of some variety. Generally the lighest possible armour would be best, but as you advance in level this would be poorer for combat, by upgrading your Light Armour and Sneak skills though you should be able to get the most advanced Light armour you can acquire though (which will also be the heaviest) and be able to wear that without any penalties to stealth due to the abilities granted by the high Sneak and Light Armour skills.

soidiers used to wear armour
If you are 1 Defence the best armour would be iron. If you are higher than 5, it hsoudl be whatever you can wear.
You cannot wear any armour into daemonheim unfortunately. Inside the activity you will receive armour. Hope this helps :)
