Dual wielding is more offensively focused obviously, and RuneScape gold it's marginally better than utilizing 2handed weapons because you get somewhat superior skills. That is why most men and women prefer using double crossbows rather than a 2handed crossbow or bow, and a wand + the shield slot offensive weapon equivalent (usually orbs such as the Spider Orb) instead of staves (except in certain circumstances where you ought to risk only one item).
So it's the equivalent of the Spider Wand since it has the exact same tier, it's the fitting off-hand offensive weapon of the Spider Wand. At your level you are probably able to purchase and wield Batwing btw, which can be even better and it's super cheap too.
It maxes out in tier 2 in f2p (was nerfed by Jagex), therefore it isn't actually the best armor in many states. You can still find adequate hybrid armor, however, the ghost hunter armor (w/e it's called) is equally as good and you will get it from murdering ghosts. Additionally there is dragonstone armor, but the price tag is pretty steep.
I believed it maxed out in grade 50. Finest f2p hybrid vehicle armour like he stated was dragonstone, that is grade 60. By the way a World Event is forthcoming this summer (May or June I believe) so you ought to have the ability to catch some warpriest then. The last time you could get warpriest was early 2014. I supposed tier two or three tiers or whatever, do not know the lingo, only an 07 participant dropping by. Warpriest armour is dreadful F2P. It's grade 50 but the stats are inferior to another grade 50'tank' armours due to being hybrid armour.
Warpriest is just decent if you do a great deal of multi PvP with clans/teams, not worth the trouble if you don't (except cape). In terms of the topic's question as others have answered already Batwing is the best Magic armour accessible to F2Pers, but you can better your weapon(s) if you're now using Batwing wand + book/shield. Gravite team is significantly better and certainly worth getting in the event that you do not plan to OSRS buy gold become a part anytime soon. It's a Dungeoneering reward worth 40K tokens, which means it'll require getting 400K exp via regular training in the Dungeoneering skill.
