Which one was the best in armor, weapon skin, and (of course) armor mod?
For armor, it would be Stalker, Pathfinder, or Rouge, weapon skin would be Operator and armor mod would be Pioneer for me!

Specializations only?
Then it’s Rogue for me.
Weapon skin, probably Arctic BR.

I believe the OP means weapon skins that came with a specialization.
As for me, my favorite specialization would probably have to WetWork. I thought the WetWork helmet looked pretty cool.
For Specializations only, my favorites are:
Armor: Tracker
Weapon Skin: Plasma Pistol (FCT) via Pioneer
Mod: Gunner Mod via Pathfinder
Armor: Rogue
Armor Mod: Wheelman (Operator)
Weapon Skin: Covenant Carbine REIGN (Rogue)
Rouge, I really like the Carbine Skin.
Armor: Tracker or Wetworks (Though I like the Pioneer visor…)
Perk: Drop Recon (Engineer)
Skin: Boltshot Piston (Sidearms are still cool)
