Guild Wars 2

So… i just hit 80 on my ranger and I´m wondering if I should farm the karma for the the Orr Temple L80 exotics or should I craft one?

In any of the case, I´m more interested in knowing which is the best stats overall
like… if it´s the best to grab a karma one, which one should I get, the same with crafting (which one should I make)

in any of the the cases I wanted to use 5 sigils of traveler and 1 pirate to maximize the magic find.

Using the Ranger mostly in W3, and therefore using longbow to offer fire support to my guild, I went with the Berserker’s Emblazoned set. I have crafted five pieces so far, and when I am done I will move to the rings, amulets, etc.
Runes of the Eagle on all pieces.

THEN, I will buy a rare Explorer set for when I don’t need top performance.

The best armor hugely depends on what build you are running. For shortbow you want condition damage and for longbow you want power. If you are looking for pure PvE armor that works with any build, you could go for Explorers’ (magic find), but as far as I know the rare set has as much magic find on it as the exotic one so you might want to save some money for your exotic DPS / whatever set and get rare MF armor.
