Well, first of all it's not exactly about "first", unless you really have mastery-fed every other weapon in the game and need a new source(which is doubtful).

Prime weapons are designed to be BiS in their field of application, so it's up to you which to make first, provided, like I said above - you are going to use it.

If that is indeed not the case, then it's all about luck. I am a new player, and overall have made hardly more than 10 void runs of various tiers\missions. I have blueprint\mats for Reaper Prime(and only lacking the damn Orokin cells), 3/4 Paris Prime parts, 2/4 Fang, 2\3 Latron.

The thing is - drop chance is pretty much guaranteed of one piece per run(whether component or blueprint). Check http://warframe.wikia.com/wiki/Orokin_Void#Rewards for the rewards and check the keys you have. It's not like a direct advice can be given, as even if you farm an item that can be obtainen from one and same mission(either with low chance, or Fang Prime - Defense Tier 1), your chance of getting Fang part exactly is shared with all other rewards.

It's also about your status with Orokin Cells. If you are a very long time player and have plethora of them you don't really need - go for 10 cell primes, less parts to farm. Otherwise it's really faster to rush-farm Void\Keys than Cells.
