In terms of speed on an rough install:
Conduit - By far the slowest method...and what happens when a location is missed or added AFTER the rock is hung? More time lost. Requires mechanical ability.
BX/AC/MC - Pretty quick, easy to work with, forgiving. People with little mechanical ability can easily perform a rough. If a location is added/changed simple enough to relocate/add.
Romex - Very quick, easy to work with, not so forgiving. People with little mechanical ability can easily perform a rough. If a location is added/changed simple enough to relocate/add.
If a blueprint (henceforth called a "map") is supplied, using either AC or Romex can be the easiest install for you. Mark the map up with different colored hi-lighters for each of the wire sizes used:
Blue: 14/2
Red: 14/3
Orange: 12/2
Purple: 12/3
Green: "Odd sizes" 10-8-6/2-3
Yellow: Cable/Tele/Doorbell wiring
The people installing do not need to know what the particular wire size is, just that they need a 14/2 from here to there, followed by another 14/2, then a 14/3 from there to another location.
If you're using Romex, use highlighter colors that coincide with the jacket color.
For straping the AC/Romex...simply use CJ-6's or "stackers", the risk of damage on install is minimized as compared to a standard staple.
