The extra time is pretty small when you look at the whole job. Bending conduit is simple and quick once you do it for a while. The connections to boxes are moot because you need them with any type of electrical connection. The only extra connections you have would be where the run is longer than 10' and you need 2 pieces of conduit.
In both you need to wire in the outlets, lights, switches, whatever.
In both you need to secure the conduit or cable to the framing
Only non-armored requires nailing plates.
Only non-armored requires an extra ground wire (copper is expensive)
Only non-armored requires connecting a ground to every box (an extra pigtail in every box)
Only conduit requires bending
Only conduit requires couplers
Only conduit requires cutting
Only conduit requires you to pull the wire (this is most of the extra time).
Only conduit allows for adding extra capacity later though existing infrastructure
The costs for raw materials between both are pretty close, but conduit definitely takes more time to do. But it isn't as much of a deal as you may expect once you do it for a while and get the hang of the tools.
I am talking about solid steel pipe, 1.5 I think would be a little underestimated.
Conduit is not solid steel pipe. 1/2" conduit can be tweaked over your knee, and in a pinch so can 3/4". It is not designed for strength.
